You have the (1) toggle on so that all CPUs are aggregated into Cpu(s). Turn off the toggle to get a separate line for each CPU. According to this your system is idle about half the time. I suspect that one processor (the one running Xorg) is going flat out and the other is idle. I don't know if Xorg is multi-threaded and able to run on multiple CPUs or single threaded where SMP doesn't help. Hopefully, the application can use the other CPU to spread the load. > Mem: 2073092k total, 1917620k used, 155472k free, 18832k buffers > Swap: 6434024k total, 0k used, 6434024k free, 1631596k cached > > PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND > 3353 root 15 -10 98128 24m 6460 R 100 1.2 10:36.02 Xorg > If you have Irix mode set, then Xorg is using 100% of the CPU on which it is running. If you have Solaris mode set, then Xorg is using 100% of all CPUs, for the time period since the last refresh. Doug. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe".
