Rubymine 2.0.1 Painfully slow on linux (Kubuntu 10.04 64bits)

Hi Nicolas,

For some reasons it's amazing slow ! Even the text editor takes time to display the keyboard input and i'm talking about the switch between thumbnails.

I had the same problem with Ubuntu 9.10 but i had fixed it after some hours looking for jvm args !

Here are my jvm args:
export JVM_ARGS="-d64 -Dsun.java2d.opengl=true -Xmx1024m -Xverify:none -XX:+UseParallelGC"

Do you have some recommendations about these args ?

You can tweak JVM options used to launch RubyMine in ${RUBYMINE_INSTALLATION}/bin/rubymine.vmoptions file.

Which package should i use to install the jvm ?

Please use sun-java6-jdk package.sun-java6-jdk

If this doesn't work, please capture a perfomance snapshot as described here http://www.jetbrains.net/devnet/docs/DOC-1144. Create an youtrack issue and attach snapshot there.

Regards,
Oleg

Yes i tryied to install sun-java6-jdk but the package is not available on unbuntu repositories.
For now I use openjdk-6-jdk.
Can it be the problem ?

RubyMine is not supposed to be launched using openJdk because there are tons of know perfomance issues.
According to http://www.ubuntu.com/getubuntu/releasenotes/1004 Sun java packages were moved to partner repository.
Add new apt repository using command

add-apt-repository "deb http://archive.canonical.com/ lucid partner"

Also please try new released Rubymine 2.0.2 final.

Hope this help!
Oleg

Ok it was that.

Develop with pleasure!
