I have also noticed, that SRSS 4.2 is terribly slow on OpenSolaris build 126. I compare it with our production SRSS server (SRSS 4.1, SXCE build 97) and other test server (CentOS 5.4). In both cases (CentOS and OpenSolaris servers) SRSS 4.2 is much slower then our production SRSS 4.1 server on SXCE. Hardware is the same in all cases (IBM blades). However, I can't be completly sure, that it is SRSS fault, because test servers use their internal disks, but production server uses EMC Clarion disk storage... The screen on test servers is drawn by parts... Quite uncomfortable for user. Disabling sock2path trick make work of OpenSolaris server comparable with CentOS server behavior, but both are quite slow.
Later we'll make some more honest performance tests (either will put system on Clarion or use SRSS 4.1, haven't solved yet).
