I like IDEs from JetBrains most of other IDEs. I often use IDEA and PyCharm And while I work with them, I spend much time on waiting IDEA's different tasks.
So is there are any tips how to improve IDEA and PyCharm performance?
In case you have performance problems with IntelliJ IDEA, refer to the CPU snapshot and thread dump instructions.
In my case, that IDE is too slow before.
Then, I try to do some changes...
On Setting Page : File - Settings...
On Appereance, this is my configuration :
On Plugins, try deactivate unused plugins :
On Updates, I turn off updates :
Configuring JVM options
I use 64 Bit Windows 7.
I go to : C:\Program Files\JetBrains\IntelliJ IDEA 2018.2.4\bin
Open idea64.exe.vmoptions using text editor, and change values of -Xmx and -Xms
This is my new idea64.exe.vmoptions config :
-Xms1024m
-Xmx2048m
-XX:ReservedCodeCacheSize=240m
-XX:+UseConcMarkSweepGC
-XX:SoftRefLRUPolicyMSPerMB=50
-ea
-Dsun.io.useCanonCaches=false
-Djava.net.preferIPv4Stack=true
-Djdk.http.auth.tunneling.disabledSchemes=""
-XX:+HeapDumpOnOutOfMemoryError
-XX:-OmitStackTraceInFastThrow
Description (Official):
-Xmx Limits the maximum memory heap size that the JVM can allocate for running IntelliJ IDEA. Default value depends on the platform. If you are experiencing slowdowns, you may want to increase this value, for example, to set the value to 2048 megabytes, change this option to -Xmx2048m.
-Xms Specifies the initial memory allocated by the JVM for running IntelliJ IDEA. Default value depends on the platform. It is usually set to about half of the maximum allowed memory (-Xmx), for example, -Xms1024m.
Change memory sizes in
<YOUR IDEA HOME>/bin/idea.vmoptions
or in
<YOUR IDEA HOME>/bin/idea64.vmoptions
if your IDEA is running on a 64 bit machine.

How can I limit the memory usage of GeoServer (v.2.21.1) installed on a Windows Server 2019?
I can't find any setting in the interface to set a limit.
In the same way as any other Java program by setting a JVM option -Xmx756M for example. See the GeoServer manual for recommended best practices
I have a Quarkus application that transforms large sets of data. At some point I always get an Out Of Memory Exception. I think when I am running the application in "Java Mode" the JVM xmx flag should work to give Quarkus more memory. Is that correct?
How can I set the memory of the application when running as native image?
When running the native binary, -Xmx is used the same way as in JVM mode.
See this for more details.
I'm on MacOs 10.13.4 (High Sierra)
Using IntelliJ 2020.3.1 (Community Edition)
I've tried increasing the heap size but failed. I've tried these two things:
Changing through the dialog box Help->Change Memory Settings. But I get stuck with the spinning cursor and have to force quit IntelliJ. However when I restart IntelliJ the memory is increased. But when I run something that requires a lot of heap size I get "OutOfMemoryError: Java heap space".
Changing directly in the idea.vmoptions file. Changing "-Xmx750m" to e.g. "-Xmx8096m". But after restart of IntelliJ I still get: "OutOfMemoryError: Java heap space".
IntelliJ->Help->Edit Custom VM Options...
I have run the exact same files in Eclipse after increasing the heap size there to 4096 mb. Therefore I know the problem isn't that the program I run need more heap space than that. To me it seems like there's no effect from the increase.
Hope you guys can help me!
You can try the following:
File->Settings->Build,Execution,Deployment->Compiler->Shared build process heap size (Mbytes)
I have a problem compiling FMU's in Jmodelica. for a medium size model I get the following error.
I already chanded the runtime parameter of JAVA in control panel and also tired setting the JVM allocated memory as high as possible using Xmx command. I'm running it on a pc with 128GB RAM.
Does anyone know how can I solve this issue in Jmodelica?
The JVM that is being used from JModelica does not take into account the system settings for the JAVA runtime parameter. You'll need to set it in the compile_fmu command. I.e.
compile_fmu(...., jvm_args="-Xmx10g")
I'm getting out of memory issues when I'm running IntelliJ IDEA 9.0.4, build IU-95.627.
My Macbook Pro has 4GB of Memory
I've heard one recommendation clearing out the ~/Library/Caches/IntelliJ90 folder is an answer..
Is that something others would recommend?
What should I set it to?
I saw this post and tried setting EXE4J_JAVA_HOME in my ~/.profile but that did't make a difference.
I've heard others say setting this too high is not a good idea as well..
Any ideas?
IntelliJ Contents/info.plist VMOptions setting:
-Xms64m -Xmx512m -XX:MaxPermSize=128m -ea -Xbootclasspath/a:../lib/boot.jar
PS: Just in case this has any bearing on things, I've been trying to use Sqlprofiler at the same time with a Grails app using the p6spy plugin in my IDE.
I usually increase -Xmx to 800m
-Xmx800m
No other changes. I don't have any problems with that in any of my projects, some of them Grails projects. Lately I have followed the EAP versions, and now I use IDEA X.
(I also have a MacBook Pro, three years old, but with 6GB RAM)
I figured out this was down to looking up a huge stacktrace.log file in the target folder.
I didn't realise how huge it was until I looked at it in the Finder window....
