JVM GC is very frequent.

We have about 500million documents are indexed.The index size is aobut 10G. Running on a 32bit box. During the pressure testing, we monitered that the JVM GC is very frequent, about 5min once. Is there any tips to turning this?

Besides frequency, you should also look at duration of GC events.  You may
want to try the concurrent garbage collector if you see many long full gc.

Some of it will also depend on things like your caches, heap size, etc.
