Jim, thanks for your advice, I agree the webrev is now against pisces:
http://cr.openjdk.java.net/~lbourges/marlin/marlin.1/ I did not check if pisces evolved since march 2013 ! Could someone give me the pisces changelog (from mercurial) ? Here is the performance summary: http://cr.openjdk.java.net/~lbourges/marlin/report/perf_summary.htm *Threads* *4* *1* *2* *4* *Renderer* *Test count* *27* *9* *9* *9* *ductus* *Pct95* 355,442 157,616 263,145 645,566 *pisces* *Pct95* 398,576 345,619 373,08 477,03 *Marlin 0.5.6* *Pct95* 130,718 129,718 130,557 131,877 *Marlin JDK9* *Pct95* 137,709 134,898 138,736 139,494 All details (benchmark log files) are published: http://cr.openjdk.java.net/~lbourges/marlin/report/ PS: do you know if hotspot or JVM flags changed a lot that could explain the small slowdown with OpenJDK9 ? I may check JVM flags using -XX:+PrintCommandLineFlags -XX:+PrintFlagsFinal ... Cheers, Laurent
