I am currently working for the first time with shopware 5, and when the editing mode is activated, my reload time is as high as 50 seconds. my colleagues say "thats how it is in editing mode", but i just cant believe them. are there any tips or tricks to speed up the process? i cant find anything :( even my macbook pro 2017 is freezing up all the time whilst working with this.
Shopware version is 5.2.19
It happens if the compiler cache is deactivated. When you deactivate the compiler cache Shopware always compiles the less files on ever request.
Go to the backend, click on Settings and open the Theme Manager.
Remove the checkbox for the Disable compiler caching.

I'm running Visual Studio 2013 Update 4 and have been seeing high CPU usages and noticeable delay on simple UI menu navigation and basic text editing.
Using ProcessExplorer I took a screenshot which shows one thread is doing a lot of CPU in something called IsAssertEtwEnabled:
The screenshot was captured randomly scrolling up and down in the Extensions and Updates window.
Any ideas how to speed up performance?
And yes I'm running several plugins, but I'd prefer to keep them, or at least find a way to isolate which one is causing this.
And I've reviewed a similar issue (VS2013 Update 3 incredibly slow - devenv.exe!!IsAssertEtwEnabled guilty thread), but I don't have anything from DevExpress installed.
Looks like this is caused by browserLink going rogue (or it was for me anyway)
You can disable it next time the issue occurs:
For me when I disabled it I immediately got my CPU back. I personally was linking to chrome though I'm not sure it makes a difference.
I guess if you use it hopefully it will be fixed in a new version...
Try to disable extensions one by one.
I fixed the issue by clearing ReSharper cache (VS 2015 CE).
ReSharper > Options > General > Clear Caches > Restart Visual Studio
#Sergii noticed that it's possible to delete the cache data directly in file system (%localappdata%\JetBrains\Transient).
I've got a relatively small project written in ASP.NET MVC3. After working a while, Visual Studio 2010 becomes very slow in Razor views (other file types work fine). With "slow" I mean "every keystroke takes around 1 second to register". It doesn't matter what that keystroke was - typing a single letter is as slow as pasting a screenful of markup. During this slowdown VS2010 consumes 1 CPU core to 100%. After I restart VS2010, everything goes smoothly again for a small while. This happens in any and all Razor views.
My PC isn't the best, but it should be enough: Core 2 Duo 6700, 4GB of RAM (currently only 75% filled with VS2010 being slow and all, so it's not a RAM shortage), Windows 7 x64.
The project is close to an end, and I remember that for most time there were no problems. This has started only recently, although I cannot imagine what could have caused it.
Does anyone have any ideas about what could be wrong and what could be done to fix it?
It is plugins - TFS/AnkvSVN and ReSharper have all caused problems for me.
Turn them off one by one, to discern which one (if only one) is causing you grief.
When you find the culprit, make sure you keep up on any patches with it.
In extreme cases, turn if off if you have a long development session and don't need it the whole time (SVN for instance could be turned on when you are ready to do commits and check ins, etc.)
The issue is resolved for me, by installing the Mvc Html5 Templates.
After the installation, I picked XHTML5 and then back HTML5 from the "Target schema" combo box. After that, the paste was instant!
Edit: I uninstalled "Mvc Html5 Templates" and the issue didn't reappear. Perhaps it has something to do with the "HTML 5 Intellisense"
Have you installed sp 1 it fixed some performance related issues when loading IntelliSense for markup
Run the Resource Monitor (CTRL+SHIFT+ESC, click Performance tab then Resource Monitor button at the bottom). Pay special attention to disk I/O and perhaps CPU usage.
Sort disk I/O by Total B/Sec descending. As you type, see if it can identify a process which is causing the issue. Hopefully it's a virus scanner or some other famous performance destroyer and not the Visual Studio process itself, which wouldn't be very helpful.
Have you tried opening the same project on a different machine? This will give you an idea whether issue is in the project or VS install. Quite obvious, but is there anything in the event viewer. Are you connected to a domain while this is happening?
Well, for me the problem has turned out to be anti virus - we use (or are made to suffer) Sunbelt Vipre on our workstations and as soon as I switch off active protection (so that's basically disabling AV completely) all of a sudden all the performance issues in all windows are gone.
Sorry for adding another answer, but there seem to be lots of different causes, so - lets list all possible fixes here.
I tried disabling ReSharper and other addons - did not work. What did work - is reapplying the SP1 again.
PS. Weird, I know. Don't ask, no idea... My guess is - VS was "repairing" itself silently at some point and restored some non-SP1 components.
PPS. You might also want to try disabling "Productivity Power Tools" addon. If you have ReSharper installed - almost all the PPT features are already there, in ReSharper.
PPPS. I have a blog post with several performance tips for Visual Studio & ReSharper, might come handy..
Have you tried Cleaning the solution?
In my case, high CPU usage started out of nowhere (WPF project). Restarts of Visual Studio didn't help, neither disabling/uninstalling addons. But Cleaning the solution did help!
I was experiencing a very similar issue on a large cshtml file in VS 2015 and was solved for me by turning off all of the automatic formatting options in Options > Text Editor > C# > Formatting > General:
I then use the "Control+K,D" key combination to format the page once I have finished making the necessary code changes.
I've been building a site, running Wordpress 3.2.1 and noticed
the performance is sluggish in the front and back end.
I believe the problem is hosting specific.
The problem seems to be the connection loading the actual HTML
which is taking about 5.5 seconds. It appears to finish after
about 500ms, but does not stop loading for 3-4 more seconds.
Here is the development URL:
http://d1001488.u57.ukisp.com/dev/
Hosting:
Windows NT
PHP Version 5.2.10
There are a couple of jQuery select boxes that get
replaced and styled onload (in the footer), these take a
long time to get replaced after the page fully loads.
The hosts are claiming all is running properly. Is there
any thing I can try and tweak or monitor to see what
is going on? Or any suggestions?
Thanks.
For largely extrinsic causes, try YSlow. This will identify a number of things you can work on. It won't tell you anything about the internal behavior of your server, but it may help you narrow down what's going on.
The problem may be a specific plugin. Here's what I would recommend:
Try going through each plugin, deactivating it, and see if that makes your site load faster. Do this for each plugin, and if a deactivated plugin doesn't improve performance then just reactivate it and move to the next one.
Try temporarily activating the default Twenty Eleven theme. See if the default theme loads faster. If it does, then we can look at your custom theme.
These two things may help narrow down at least where the problem is coming from. Let me know how it goes!
Do you have CPanel access with your hosting account? If you do, look in the left side toolbar at the bottom you should see where it says server status (click to view) you will see various details about your server performance.
I'm using Eclipse Galileo with latest GWT 2.0 version in development mode, but it runs really slow (I need to wait about a minute to open one page, but after compilation, my application works very well when I run it using Tomcat 5.5).
My code is not too heavy and I guess there is an OS-related or software inconsistency problem, because I'd this problem before, but when I reinstalled Windows Vista SP2 (I formatted my Windows drive and reinstalled it), my problem was resolved for a few days and then again it became too slow.
I didn't install any special software on my Windows machine, so I really don't know why this problem occurs. Any suggestion ?
If it has become unusually slow, but was faster previously, and you are debugging, that might be because you have a breakpoint set on a method entry. This can make things extremely slow, even if the breakpoint is not hit. Try clearing your breakpoints.
If you're using smartgwt make sure firebug or similar is disabled. That will really slow down your browser in dev mode.
And as far as NetBeans is concerned there really is a plugin for GWT called GWT4NB. But the IDE is not your problem :)
First time you load the page, it loads all the necessary javacode (and the JVM). Later, each refresh of the page will only loads the changed javacode then execute the whole (I might be wrong though). So if you're closing the browser then reopening your page each time you want to see the changes you made, yes it's going to be slow. If you refresh the page each time, it SHOULD be fast (if the changes you made weren't huge).
Eclipse + GWT 2.0 is not the reason why it's slow... (by the way Shubhkarman, if I'm correct there is no GWT plugin for netbeans...)
Delete gwt cache from temporary folders like images. rpc files..etc. than see the performance. it is one of the cause to slow in hosted mode.
I've found that the performance difference between running the GWT hosted mode in debug vs. non-debug to be large. If you're running with debug, try running without to see if that helps.
The initial page load can be slow, but once you get going just clicking refresh on my browser reloads the updated project in just a few seconds.
I had similar kind of issue and I found that it was happening because of number of break points. After reducing number of break points performance got improved.
Even I had the same issue with GWT. I've started testing with firefox now. first time when I ran the debug on firefox, it was slow.
I set the log level to 'info' in the runconfig > gwt tab
So, I restrated my workspace and the firefox. Then 'debug >myGWTapplication '
When you open your application on debug mode, wait for the browser plugin to connect now.
This time it does not write all the log lines in the development mode, and it is faster.
I think the firefox and the logging has made the differance. Now I do not see much lag.
Also as mentioned in the above comments, remove the debug points, i've removed all, and use then when necessary.
Edit: tried it on the IE8 - it is fast event there.
as the single user / developer on a drupal website im experience serious performance problems. several issues occur:
usually i develop drupal on our company dev server but now im at a client's office. the IT guys installed a VM with WAMP on the server they usually use for .net development. on the first day of dev (installing drupal, required modules and configuring them) httpd.exe would max out the cpu and loading any page would take minutes. IT guys just scratch their heads.
i then just installed WAMP on the local machine they gave me: some 299,99 Win XP Dell piece of sh*t, nevertheless a P4 2.8Ghz 2GB Ram. the fan blows so loud the entire office is giving me dirty looks. Again httpd.exe maxes out. again, any page (esp admin ones) takes minutes to load
in firefox, the views UI is completely unworkable. alot of stuff is loaded with ajax and it again takes minutes to see the various html elements dynamically inserted in the UI to appear - try to imagine this.
Chrome seems to handle the JS a bit better but it still takes way too long to complete any kind of action.
the devel_themer module ads tons of markup to the page which leads to "Allowed memory size of X exhausted" errors (memory_limit = 128MB ).
now im at the themeing stage where i need to do a LOT of page refreshes. I NEED firebug which requires firefox which in its turn eats up CPU and RAM. What usually takes seconds now takes minutes and by the time whatever action is completed, i forgot what i was doing. im basically reading news stories in between every page reload.
now, i know drupal is resource intensive but that its impossible to develop on a typical Dell / Win XP machine is a bit much, no? at home i work on an iMac and everything runs silky smooth.
i cant imagine im the only guy with this problem since what im doing is basically drupal 101 (no custom modules so far ...). unless someone can offer a solution, im concluding that you basically can not develop a typical drupal site on a normal home desktop computer.
what gives?
So you have abandoned the VM,check you php.ini file for the memory limit, increase it and see if there is a performance boost. its usually set to a default of 16M.
HTH
I'd suggest you either make sure to spend some time actually tuning your XP system, because the default WAMP config is definitely suboptimal, or consider an alternative, like Zend Server community edition (ZCE). Although not completely free as in speech, it is free as in beer, and simply builds up on top of a better default config for Apache and MySQL.
Although less convenient than WAMP or ZCE since not bundled, a manual install of Apache 2.2 is also usually a good choice.
Also note that, that the way devel_themer works, it is constantly building files in your temp directory, meaning that unless that directory is cleaned regularly, files will accumulate and directory browses will become exceedingly slow. Only a cron.php run will cause drupal to clean those files, for an up-to-date version of devel. See my patch adding this cleanup at http://drupal.org/node/303443
Finally, you mention Firebug, and you might be using the Drupal for Firebug module, which has known performance issues, apparently related to infinite recursion in some cases; although recent versions are supposed to fix this problem. See for instance http://drupal.org/node/303443
A couple things I've run into that could potentially help.
Unless you actually need it, turn off Locale. It causes a ton of extra queries (at least the last time I looked into it, this may have changed) so if you're not using it then don't put the unnecessary load on your DB.
Just like on a regular development machine, make sure MySQL is properly tuned and configured. This goes for any setup; local, development or production. 3/4 of the time the database is the bottleneck so start there.
If you've got the devel module installed and enabled it should have a query log you can tell it to output at the bottom of the page, this should help you with number 2.
