Description Alexander Simon 2015-07-24 08:05:54 UTC
According to performance tests "openjdk-perf-linux" IDE has a significant performance degradation.
Memory footprint for JDK project increased on 70%.
Parsing speed decreased in 4 times.
This is example of performance report before:
Threads	Memory	Speed (LPS)
1	443	22808
2	423	27774
4	363	31920
This is current state:
Threads	Memory (regression)	Speed (LPS) (regression)
1	779 (x1.76)		5275 (x4.3)
2	653 (x1.54)		6560 (x4.2)
4	692 (x1.91)		6143 (x5.2)

I see small progress in parsing speed.
But it still 4x regression
