There is a 2GB contiguous memory limit > on linux, so try sizing the heap at 1.6gb. > For the hotspot JVM the flags are: > java -server -Xms1600m -Xmx1600m > > more advanced options are available if GC is a bottleneck. > First, try AggressiveHeap. > -server -Xms1600m -Xmx1600m -XX:+AggressiveHeap > > AggressiveHeap turns on ParallelGC, TLABs and sizes the young > generation, along with a few other platform and competitive benchmarking > specific flags. The important flags to try are: > > -Xmn400m (size young gen. to 1/4 overall heap size to start) > > -XX:+UseParallelGC > > -XX:+UseTLAB > > Cheryl Thanks Cheryl, I forwarded this to our Java programmer.
