GC performance regression between 7u11->7u45?

[Srinivas Ramakrishna]

Is anyone, especially the perf and gc teams inside Oracle, aware of any
parallel young (PS) gc performance regressions
from 7u11 to 7u45?

I am seeing some 20-30% regression in minor gc times (and a lesser increase
in promotion volume per scavenge),
on some random testing of a largish application. Haven't dug into the
details yet, but wondered if this was noted
on any of the Oracle perf/gc or community perf/gc radars and if there's any
guidance available.

As I delve deeper the nature of this apparent GC regression, which I just
became aware of, I'll post more.

thanks for any help!
