Set/Increase Memory Available in Rubymine
I did not find anything to love about the results I was getting searching for queries like “Increase rubymine memory” and “set rubymine memory”. Here’s the location of the file that dictates Rubymine memory usage in my Ubuntu install:
[RUBYMINE_DIRECTORY]/bin/rubymine.vmoptions
Inside you can specify lines like:
-Xms800m
-Xmx1200m
-XX:MaxPermSize=1000m
-ea
These declare maximum memory usage, maximum sustained memory usage, and, uh, some other stuff.

I love Rubymine, but I sometimes wish that instead of adding a ridiculous number of new features, they’d just make the damn thing run consistently fast, and not make me worry about memory usage. I know that with my web site I always have a preference toward adding cool new stuff, but responsible thing to do is often to perfect the pieces that are already there. Almost everything negative I’ve heard about Rubymine (which isn’t all that much) is along this same vein, but I’ve never heard the Rubymine team admit that it wishes that the product ran faster or its memory management were better.

For my money, still definitely the best choice for Linux IDEs.
Hi,
Actually there is absolutely no sense in increasing max permgen size (-XX:MaxPermSize). Also if you don’t prefer to open several big projects simultaneously, there is no sense in increasing -Xmx (max heap size bound) more than 500 mb. May be exceptions is only 64bit jdk which requires about twice more memory comparing with 32bit version. If you increase -Xmx GC for larger heap will be invoked a bit rare but each GC collection (GC pause) will be much longer. Sometimes it is reasonable to send memory snapshot to RubyMine team (see http://www.jetbrains.net/devnet/docs/DOC-1144) instead of patching -Xmx.
P.S: On MacOS instead of vmoptions.exe you should change -Xmx in /Applications/RubyMine.app/Contents/Info.plist
