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.
[Hops onto soapbox]
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.
