Yes, somewhat exact behavior I'm seeing. Below is the hardware config of our machine. We ramped up 1user every 10sec up to 100 users and the 100 users stayed 30 mts executing bunch of portal actions. I see spikes at 28th minute with just a Hello World portlet. I'm also investigating JDK1.4.x and Borland 5.x to see any cause. will post you with more information. thanks a lot System Configuration: Sun Microsystems sun4u Sun Fire 280R (2 X UltraSPARC-III+) System clock frequency: 150 MHz Memory size: 4096 Megabytes ========================= CPUs =============================================== Run E$ CPU CPU Brd CPU MHz MB Impl.
