Hi Ian,
I've been pretty frantic just trying to get the perf regressions
presentable, and have not had a chance to look at the sanity
regressions. The chart regression is the well known Classpath gtk
one, I suspect (since I did not want to give any of the VMs
dispensations---they are just running out of the box... ...or not).
Actually this is not quite true---I had to explicitly set -
X:processors=all for us to get competitive performance. I've lost
track of the status of that. I wonder why all is not the default
(rather than 1).
Once I have the sanity regressions on line (in a few days), it should
be easy to investigate and get something in the trackers.
