-----------------------------------------
[~ste...@apache.org] - I have been playing/working on java 11 since last few
months and have seen some *serious performance degradation, On Java 11 -*
Tera gen took 4 minutes, and 32 seconds as compared to 3 minutes, and 28
seconds on Java 8.
Tera sort took 10 minutes, and 55 seconds on Java 11 compared to 8 min 32 sec
on Java 8.
Any ideas/suggestions on this? Did you guys face the same issue. Also tried
various things like changing the GC etc but nothing has really helped in
performance improvement yet.
