I just setup a new Wordpress blog at home, and no other pages takes forever...I am trying to just add an image to the post, but it is just taking forever...none of the other pages takes so long to load...
And i have just optimized all my tables via mysq and a scheduled task, so i don't see why it's taking so long to load...
I am experiencing EXACTLY the same issue...
here is what I did to boost the performance by 5x
I added my Google Analytics code into the GA plugin
I would guess that if you have implemented GA... you could also disable it too!
since GA displays on the edit posts page, it was slowing down my page display
taking up to 20 secs to load!
now the entire page loads in under 4 secs

The backend of Magento ranges between slow and super slow when editing.. opening an item for changes and saving an item following editing. Sometimes it can take minutes! It has always been slow.
The issue with the page slow to fully open, It takes around 6 seconds to load the page image and the image flash at 6 seconds.
The cart takes more than 5 seconds to download.
Slowness of Site depends on the Work has been done on Magento.
Following are the steps you can do to increase the site speed -
Enable JS and CSS Minify
Enable Caching
Enable the profiler to check the exact files and event which are taking time and then debug the code -
Use Command to enable Profiler - php bin/magento dev:profiler:enable
Once you enable the Profiler then see the events at the below table of pages.
If you type in cache:www.92spoons.com, for example, into the Google search engine, it shows you a snapshot of the page from a time when Google snapshotted the site. I was just wondering, how often does Google refresh its cached data? It looks like, as of now, it was refreshed about 3 days ago. Also, do all sites' cached data update at the same time?
This is based on how often the website is changed. For example, Wikipedia may be updated several times a day, but 92spoons.com may be updated every few days. (source)
This also can be changed by popularity. You can visit this website which should allow you to refresh the cache. (source)
I am facing a very strange situation and don't know how to solve it...Please help me solve the issue...
I am working on a web site where a research page is created to measure the performance of tasks done in the web site. It is one type of report page which checks for different conditions into the database tables, retrieves the information and send an email to the administrator. The page runs in every hour that is 24 times per day.
Now what the issue is: The web site works correctly however when the research page runs the other pages of the web site do not work correctly. That is say for example I am on the Page1 and at the same time the research page start running. Now at this time - when research page is running - if I click on the link of Page2, the Page2 will not get displayed until research page finishes its working. Can anyone tell what could be the issue for this behavior?
Here are some more information regarding the issue:
The web site is in Visual Studio 2008 (C#) and SOL Server 2008 is
used
The SOL query is too complex for research page however, I have made
all the optimization which are possible.
There are two connection strings (with different user for same
database) used in the web site. One for the Research page and second
for all the other pages in the site
Please help me find out the issue... Thanks in advance....
This may be due to mishandling of the Thread within you website. Have you tried it by Threads and Building Asynchronous Handlers in Your Server-Side Web Code
Just check out this might help you with :

I have built a test website using nopCommerce open source , Everything is working fine , i need to know , why my website loading time is greater than 6 sec , the homepage works fine but the categories when clicked takes like 6-10 secs. how can i check the http request and calls to db so that i can track which function is taking a long times.
Test website is test website
Thanks
Things I would try in that order:
MvcMiniProfiler.
Analyze my code for possible performance bottlenecks using a .NET profiler.
Finally submit bugs to the nopCommerce support if the previous approaches didn't yield anything fruitful that would put my code into cause.
In between I might also checkout with my hosting provider whether he is not the cause of the slowness.
As a quick and dirty check, you can add the time it takes to generate the response as a column in the IIS logs - that will give you some idea as to whether the server is being slow to serve the pages or you need to do some front-end optimisation work.
On the front end side the first thing you need to do it merge all the CSS files for a theme into one to save on roundtrips - the browser can't render the page until it's got the CSS
All the .js files you have in the head will also block the page, can you merge them and load them later?
The performance of imagegen.ashx looks on the slow side - do you need to generate the banners on the fly or could they be pre-generated?
If the back-end side of generating the page is slow, there are some scripts around the web to show which queries are using the most CPU, making the most IO ops etc.
Below is a list of things you can improve,
1.Combine your js.
There are a few things you can use, for example, jsMin, you can read this [post] http://encosia.com/automatically-minify-and-combine-javascript-in-visual-studio/. However, jsmin doesn't seem to compress the combined js.
Another option is [jmerge] http://demo.lateralcode.com/jmerge/ It kinda does it after the fact, in the sense that you need to have the site ready to cobine them with jmerge since it only take a http link.
The best one I'v known so far is bundling and minification feature of MVC4. It's part of MVC4, however, you can get a Nuget package for you MVC 3 app.
Word of advice: bundling every js of yours is not necessarily a good idea, it even backfires someimtes, since you will end up with a big js that browser will have to download sequentially, instead of downloading several smaller ones. (you might want to look into head.js to make js download parallel) So the trick here is to keep the balance. I end up have a jquery from google CDN and bundled the rest of my js into one.
2.Put js at the bottom of the page so the browser doesnt have to load the js first before it starts to render the page. But you need to be careful with this one though, since normally you will have jquery functions doing stuff upon document.ready() at the header of the page, I adviese you moving that to the bottom of the page as well, if possible.
If you move the js reference and scirpt block in you layout page to the bottom, then you will most likely run into problem with nested js reference and js script blocks in your individual view. No worries, then you need to look into using #section (probably suitable for a discussion in an other thread) in your view and render it in your layout page, so that the referenced and script block inside your view get rendered at the bottom of the page at run time.
2.Use CDN
Pretty straight forward.
3.Combine CSS
Combine them into one, with the same tool you use for combining js, but you need to reference it at the page header, instead of the bottom.
4.Enable static content cache, something like this in your web config file
It won't help with first time load, but definitely will make it a lot faster for returning user.
5.Enable url compression
Time to first load
This is one of the metrics used by webpagetest.org. But dont bang your head against this one too much, as it basically says how fast your web server can serve the content. So probably not much you can do here form the software end.
Hope that would help!
NopCommerce is deadly slow, and the developers doesn't look in to the performance issue seriously. I have seen lot of performance related forums left unanswered. So best luck.
I use the Kohana3's Profiler class and its profiler/stats template to time my website. In a very clean page (no AJAX, no jQuery etc, only load a template and show some text message, no database access), it shows the request time is 0.070682 s("Requests" item in the "profiler/stats" template). Then I use two microtime() to time the duration from the first line of the index.php to the last line of index.php, it shows almost very fast result. (0.12622809410095 s). Very nice result.
But if i time the request time from the browser's point of view, it's totally different. I use Firefox + Temper data add-on, it shows the duration of the request is 3.345sec! And I noticed that from the time I click the link to enter the website (firefox starts the animated loading icon), to when the browser finish its work(the icon animation stops), it really takes 3-4 seconds!!
In my another website which is built with WikkaWiki, the time measured by Temper Data is only 2190ms - 2432ms, including several access to mysql database.
I tried a clean installation of kohana, and the default plain hello-world page also loads 3025ms.
All the website i mentioned here are tested in the same "localhost" PC, same setting. Actually they are just hosted in different directories in the same machine. Only Database module is enabled in the bootstrap.php for kohana website.
I'm wondering why the kohana website's overall response is such slow while the php code execution time is just 0.126 second?? Are there anything I should look into?
==Edit for additional information ==
Test result on standard phpinfo() page is 1100-1200ms (Temper data)
Profiler shows you execution time from Kohana initialization to Profiler render call. So, its not a full Kohana time. Some kind of actions (Kohana::shutdown_handler(), Session::_destroy() etc) may take a long time.
Since your post confirms Kohana is finishing in a 1/10th of a second and less, it's probably something else:
Have you tested something else other than Kohana? It sounds like the server is at fault, but you can't be sure unless you compare the response times with something else. Try a HTML and pure PHP page.
The firefox profiler could be taking external media into consideration. So if you have a slow connection and you load Google Analytics, then that could be another problem.
Maybe there is something related with this issue: Firefox and Chrome slow on localhost; known fix doesn't work on Windows 7
Although the issue happens in Windows 7, maybe it can help...
