Platform tested : Linux 7.1
Build 81 in comparison to Build 80.
Hardware Pentium-4
J2DBench shows Opaque scaled images are much slower on Linux 7.1 on b81 than on b80. Please refer to Test reuslts for build 81 at :
http://xanadu.india.sun.com/~mg121047/j2dbenchb81/j2dcomp.html
Scaled Opaque images are 10 X slower on Linux 7.1 b81 than on b80.There is a certain performance improvement though for nonscaled (original size) images .
My Observation is that while BitMasked images (non scaled ) have one up in terms of performance to about 3 times Scaled bitmasks have come down three times. (Scale can be 0.5 time the original size of the Image or 1.5 times the original size )
I have not had time to regress the bug any further , shoudl you want me to do it I shall be pleased to help you . A latest copy of J2DBench is as attached .
J2DBench can be run as per procedures to be found :
