Hi solr addicts, I know there's no one size fits all set of options for the sun JVM, but I think It'd be useful to everyone to share your tips on using the sun JVM with solr.
For instance, I recently figured out that setting the tenured generation garbage collection to Concurrent mark and sweep ( -XX:+UseConcMarkSweepGC ) have dramatically decreased the amount of time java hangs on tenured gen. garbage collecting. On my settings, the old gen. garbage collection went from big time chunks of 1~2 second to multiple small slices of ~0.2 s. As a result, the commits (hence the searcher drop/rebuild) are much less painful from the application performance point of view. What are the other options you would recommend? Cheers!
