The page size is set to 50,000.
Okay, that was strange. 50K is fine for a heap. How many concurrent
searches are you running?
Just one search at a time, although the index searcher is passed an
executor with a thread pool of 16 or so.
What are the best JVM collector settings for Lucene searching? We're
tried various options and they don't seem to make much difference.
I am no expert there, but I will advice you to check how much free
memory your JVM has when it is running searches. GC-tweaks does not help
much if the JVM is nearly our of memory.
There is a plenty of memory available. The heap is set to 6 Gigs.
