Has anyone ever experimented with the AggressiveHeap option (-XX:+AggressiveHeap) option? Looks like it was released with 1.4.2. Rich

My understanding is that AggressiveHeap is for really big heeps, like gigs of memory, and it's not suitable for smaller apps. But I'm no GC expert. Are you having some scaling issues? - Charlie --------------------------------------------------------------------- To unsubscribe from this list, please visit: http://xircles.codehaus.org/manage_email

We were hitting up against some outofmem issues, but then adjusted the Xms, Xmx, Xmn, and MaxPermSize and seem to be back in business. I've been playing around with some of the tuning recommendations found in this white paper -> http://java.sun.com/performance/reference/whitepapers/tuning.html Seems to be pretty old (12/2005). Does anyone know of more recent tuning tips? Might be good to add performance tuning flags inside the http://wiki.jruby.org/wiki/Performance_Tuning page. I'll add our settings once we get them nailed down. Rich On Sat, May 10, 2008 at 12:34 AM, Charles Oliver Nutter
