Most commercial Java appsevers (ATG Dynamo, etc.) recommend using a green
threads (i.e. single CPU) Java VM and I think JServ runs best this way too. Just
create one VM per cpu (i.e. 12) and use APJServBalance, no worries.
Sun's native threads VM's were optimised for a max of 2 CPUs (1.1.7) and 5 CPUs
(1.1.8) respectively IIRC. Have you tried JDK 1.2 ?
Number of users depends on your app - we get simulated load of about 150 c.u.
per VM on our app, where each VM is 256Mb running on a 600MHz Intel P3
