I am very new to Julia and am not a computer geek so this question may not be very clear. I am happy to add any information as necessary.
I am running Julia on VSCode in Windows. I recently added some memory sticks (128G to 256G) to the PC and found out that Julia was significantly slower. I tried several things including moving the positions of the memory sticks, reinstalling Julia and VSCode, disabling hyperthreading. (in this order). Nothing worked.
I then decided to install Windows Server on my computer, hoping that Julia would behave normally under the new system. It was still slow.
Could anyone give me some suggestions on what to do? Thanks!

Longshot, but anyone had this issue?
I have code running (or not) which is set to run on the GPU. It fails to run unless I bump the GPU to make it run a little bit, for example by watching YouTube or playing a game.
I believe there may be some computer resource/application prioritisation/limitation configurations causing vscode to stop running, and wondered if anyone else had run into this issue.
I am running the code in a .ipynb notebook file in vscode (not sure if that might contribute to the issue). Sometimes the code will just freeze permanently, and I usually go about restarting the code to get things going properly.
The code should normally takes about 7 seconds for the training epoch, and 0.7 seconds for the validation epoch. But I was away for the first epoch and found it hadn't started, and so I opened up Youtube and it began.
Code timings
I can't think of what settings to change for this, but have tried a few
Power options
Anyone had a similar issue before? My second theory is that I think perhaps I am using too much GPU ram in my python code which is slowing it down and effectively made it freeze. And then when I load another application to use the GPU it forces the GPU ram to reconfigure and somehow this RAM reconfiguring might be unblocking the GPU allowing it to run again.
Since some years ago I started using Qt in both Windows 7 as well as in Linux Ubuntu and it would always compile fast with MinGW being used for Windows. But in the last couple of years or so, maybe thanks to updates in the version of both Qt and MinGW, I started detecting a slow down in the compiling speed inside Windows. I did some research trying to find why MinGW had started to become so slow compared to Linux (it wasn't before!) and everything people told me was that MinGW was slower in Windows and that it would be better, if possible, to just use Linux.
Since I wanted to continue my project, I followed the suggestion and since I've being using Linux with relatively no problems. The situation now is that I must go back to Windows (now updated to Windows 10) to make visual corrections for this OS and I need to once again work with MinGW having to face the same problem as before.
But for some reason it seems that the slowness of MinGW became even worse! While before I at least was able to compile the app in around 4 minutes, now the last time I tried it took 38 minutes before I gave up and went to sleep - and this is for a project that takes only 1:03 minute to be compiled in Linux [under the same compile configuration]!
Well I'm still aware about the slowness of MinGW, but as a quick research around this problem on the web reveals, that is just too slow: all backtesting one can find in other threads here on SO reveals at best 2x-3x more time to compile a project, not 38x+!!
So I would like to know what kind of possible problems I might have in my Windows for this exaggerated slowness to happen. I know I ended up installing at least 4 different versions of MinGW; could this have brought the problem?
It's interesting also to notice that when compiling using the -j option and watching the Compile Output log in Qt Creator alongside Process Explorer, there are moments when the compiling simple pauses for 10 seconds or more and the CPU usage drops from its ~100% to close to 5% with nothing happening till it suddenly continues the compilation process. I'm sure this constant pauses are part of the above average time, but I have no idea why MinGW is showing this behaviour.
You might want to check where the time is spent.
There a lot of tools that allow you to capture what a certain process is doing, I name just two of them:
ProcMon
XPerf or its successor
But to analyze the reports generated by these tools you need a rather deep understanding. If this doesn't help temporarily disable other running services and program step-by-step (if you want to know which program causes the problem) or disable all of them at once.
Looking at the spikes of cpu usage that TaskManager or Procexp by sysinternals show might help too to identify those components that block your cpu.
If your antivirus is the cause of the collision that makes the compile so slow you can define exceptions, then the antivirus will not scan certain programs or paths.
So perhaps it is easier to first try the compilation process with a disabled antivirus software or even from a clean live boot Windows CD.
I'm having a very strange problem. I'm using dfs-datastores Pail abstraction to write data to HDFS in Java. I don't think the Pail piece is important to the problem though.
When it calls org.apache.hadoop.fs.FileSystem getFS(java.lang.String path) with a path on my local filesystem it pauses for about 2 minutes seemingly doing nothing then returns. This is on my laptop.
The weird thing is that it worked really fast when I was on the network at my office today, but now that I'm home it's doing it again. I'm running Ubuntu 10.10 64-bit with Java 1.7.
Anyone have any ideas what it's doing? What could be different between being at work and being at home?
UPDATE:
I've been stepping through code with the debugger and it seems to be having trouble in Configuration.loadResource(). It's calling that multiple times and it will take 5-10 seconds to return from that function.
UPDATE2:
I've narrowed this down a little further. The biggest hang up seems to be when it calls KerberosName.setConfiguration(). Which would explain why it runs fast at work since the Active Directory acts as a Kerberos server. I don't have one here at home, so it can't find one. Now they question is why in the world it's trying to load the Java Kerberos stuff.
I found a solution (or at least a work around). I installed the krb5-kdc package and now my little program runs fast without any unexplained pauses. After this I removed krb5-kdc, tested and it was still running fast. I removed /etc/krb5.conf and it started doing the pause again. It looks like using the Hadoop library on Ubuntu (at least) requires a /etc/krb5.conf file.
Maybe this will help someone else.
Im using ReSharper 6 in a Vs 2010 Pro environment and are doing some pretty large scale projects. Development box includes 2 x quadcore xeon with 24 GB ram. Project's are running on a PCI-E x4 SSD drive with 1GB/s read and write (for real). So, i suppose there is not much I can do to give the development machine more power.
The worst project is an Umbraco site with roughly 14000 files and folders and some pretty nasty css. I got everything from second long freezes to 30 sec VS freezout.
I've optimized VS2010 according to every guide available in VS optimization. Even enabled the 64bit memory enhancement but the problems continue.
I've even added the media library folder to the skip list.
Are there any other magic tricks someone would know of, please let me know!
gorohoroh's comment lead me to the solution, the 6.1 nightly dec 13 rocks!
Thanks

I am using 7.0.1 and I find that it's killing my machine too.
However, it normally happens if I have more than one VS2010 open.
If it happens then the only way of fixing it I have found is to close VS, delete the DotSettings.user and the suo, and then reopen.
I'm using 6.1, and find that it slows down over time, and typing becomes really laggy. I've just discovered that when it starts to chug, if I go to "Tools..Options..ReSharper..General", then click on Suspend, then Resume - it goes back to it's initial speed.
I installed Eclipse Galileo and after trouble with the JDK, its starting well. But I have big problems with performance. Every third second, Eclipse is hanging for a while. It runs not smoothly. I need a efficient IDE as Eclipse for work. So, it would be very nice when you have a fast answer :)
Both Eclipse as the JDK are 64-bit versions.
Have you any ideas?
Update:
I can´t really explain the problem from scratch. But in my case, it was a trouble between Eclipse´s and the auto-complete-function of my OSK. If I disabled auto-complete, there was no hangs anymore. I don't know why the using of the OSK blocks the thread (?) of the whole editor.
Maybe anyone of you, has an idea why?
From your description it sounds like the garbage collector is being triggered. How much RAM have you got in the system? Depending on the plugins you're loading Eclipse can need quite a lot of it. I think the bare minimum is 256 Mb, and realistically you need at least 1 Gb, more if you're doing web development
Have you got an up-to-date JVM? Eclipse generally runs much quicker with a 1.6 JVM.
One other thing to check, do you have an aggressive virus scanner? Eclipse plugins are collections of small files in jars, some virus scanners can really slow down the performance. If you are able, remove the Eclipse install directory from the scanned files.
See this EclipseZone article or this question for some general performance tips.
Run Process Monitor and see what kind of system calls and/or file system calls the JVM is doing. Use filters aggressively to pinpoint a specific process. I had a similar issue where a graphics card utility triggered a flood of registry lookups for every UI update which just made Eclipse incredibly slow. (Somehow SWT was hit exceptionally hard by this bug, I'm not sure why.)
EDIT: I meant "Process Monitor", not "Process Explorer". But the link was correct.
You could try to run it from within a virtual machine set up on your computer to see if the problem is still there. If it's not, it might be faster for you to just work from within the virtual machine environment. Doesn't address the issue, but it may help avoid it altogether.
I had same problem so I just switched to the 32 bit version of Eclipse and it runs fine with no performance issues.

Same problem for me
I have Windows 7 professional 64 bit and 8gb of RAM
Eclipse is extremely slow, probably 5 times slower than the Windows Vista 32 bit machine I have recently upgraded from (Europa version) - and that machine was a complete dog!
Adding -Xmx1024m -XX:+UseParallelGC -vm C:\Program Files\Java\jdk1.6.0_20\jre\bin\server\jvm.dll has made a pretty big difference
I have same problem as not respoinding.
I searched in internet for a solution. I found one by adding the below to
eclipse helios config file.
-vm
C:\Program Files\Java\jre7\bin\javaw.exe
Initially it looks Ok to start and click on the different buttons and
running on several files in eclips project. But when I click on debug
and step by step process. Then it is again showing not respoding.
I have a new laptop win7 installed.
I have the same problems with the 32 bit version, running with a 32 bit JVM.
It's more that my RCP Application which I developed with Eclipse is slow. I've tried both -Xmx1024m and -XX:+UseParallelGC, with no noticable effect. Has this issue been registed with eclipse.org?
