Thanks John, don't jump right in to my report. I'll look into it more and
I really don't want to sidetrack you.
I did run with several flag choices ( server, tiered, debug agent ) and
found
only about a 10% difference after I let hotspot stabilize. I am pretty
sure
I don't have Christian's patch so I look forward to more. My best setup
is 687/450 vs standard Java. For whatever reason the repeatable slowness
of yesterday is not apparent today.
Is there any way from within ( or from a debug agent ) to tell hotspot to
forget all optimization?
I also see a few of these.
430 COMPILE SKIPPED: invalid non-klass dependency
704 COMPILE SKIPPED: out of nodes parsing method (not retryable) (
server mode )
1623 COMPILE SKIPPED: out of nodes parsing method (retry at different
tier)
I am going to retrace yesterday's setup to see where the 4X slowdown came
from
regards
mark
