if you want to see the gory details, look at AdaptiveSizePolicy::check_gc_overhead_limit() (line 471+) in http://hg. openjdk.java.net/jdk8u/jdk8u60/hotspot/file/37240c1019fd/src/share/vm/g c_implementation/shared/adaptiveSizePolicy.cpp Thanks, Thomas _______________________________________________ hotspot-gc-use mailing list hotspot-gc-use@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/hotspot-gc-use
