JVM fine tuning options for Intellij/Linux.

Hi,

Is there a list of JVM flag options that can be used to fine tune Intellij performance on Linux?

Some of the issues we face are:
1. Rendering is slow over NX
2. Some times Intellij takes noticeable amount time to respond to key strokes.

We are using -Dsun.java2d.pmoffscreen=false and observed some improvement in rendering. Are there any other such flags?
Is it safe to use -J-Xverify:none (which disables byte-code verification) during development of code? Has anybody tried using -Xshare:on, are there any issues with using these flags?

Thanks,
Chandra
