I am using Glassfish-v2-u2 on RHEL 4 (2.6.9-67.ELsmp x64) with java 1.5.0_14-b03. On all default settings, in full load, glassfish seems to be using only one CPU of 4 core machine.
The application code seems to be ok, while on similar setup on Windows x64, all 4 cores are used and the TPS of the application is rougly 4times better as well.
Can you please advise some settings that can help improve performance (cpu utilization) on linux box? Thank you.
