Hi Alexey,
we ran tests with 2.1.11, 2.2 and 2.3-SNAPSHOT
The result is performs 2.1 ~15% better than 2.2 and 2.3:
grizzly 2.2
http://hammercloud.cern.ch/hc/app/atlas/test/20009667/
girzzly 2.3
http://hammercloud.cern.ch/hc/app/atlas/test/20009668/
grizzly 2.1
http://hammercloud.cern.ch/hc/app/atlas/test/20009669/
(look at the mean of most right graph)
The only difference in the code is attached. May be problem is there.
Regards,
Tigran.
