Thanks for the report, Kirill.
Could you run your app with J2D_TRACE_LEVEL=4 env. variable set
on those machines and post the output?
Also, could you run with -Dsun.java2d.d3d=false on both b21 and b22
and see if you still see a difference?
There were a couple of fixes which could have caused
this - one is d3d-related, another is text rendering loops
fix.
Thanks,
Dmitri

After installing b22 on two Windows machines i see a performance regression of about 15-20% on the same internal benchmark that i'm running. The benchmark is just stressing Substance look-and-feel on different control types and includes a lot of Java2D operations, composites, translucencies, text painting, gradients etc.
The code is the same between b21 and b22 and it's not something that i can post
in the forum. To reproduce you would need to download the Substance
distribution and run the test.perf.PerformanceSuite. It has a warmup stage when
it's repainting the same frame 10 times, and then paints it once again, timing
the painting time. It does so on three tabs and just prints out the average
painting time. The code is the same, the OS is the same, but the 6u10 build is
different.
