IIRC, Xeon processors have dual internal cores (or at least dual=20 instruction decode paths), and act like dual processors, and benefit=20 from the SMP kernels. Also, IIRC, there were both P3 and P4 Xeons made= =2E=20 So, you have to know which version you have. What does "cat /proc/cpuinfo" tell you? --=20 Kevin J.
