<div dir="ltr"><div><div><div><div><div><div><br></div>Is anyone, especially the perf and gc teams inside Oracle, aware of any parallel young (PS) gc performance regressions<br></div>from 7u11 to 7u45?<br><br></div>I am seeing some 20-30% regression in minor gc times (and a lesser increase in promotion volume per scavenge),<br>
</div>on some random testing of a largish application. Haven't dug into the details yet, but wondered if this was noted<br>on any of the Oracle perf/gc or community perf/gc radars and if there's any guidance available.<br>
<br></div>As I delve deeper the nature of this apparent GC regression, which I just became aware of, I'll post more.<br><br>thanks for any help!<br></div>-- ramki<br></div>
