Fedora on Xeon slow?

    We have a couple of PCs at work, both running Fedora Core 1 and using 2.4 kernels. Mine is a P4 3.0Ghz w/hyperthreading with 1.5GB of RAM, and the other is a dual Xeon 2.8 Ghz w/hyperthreading with 3.0 GB of RAM. We're doing some Perl development on them and the Xeon machine seems to take about 20% longer to run the same scripts than the P4 machine. I know this is a vague question, but anyone have any insight? Is Fedora (or Linux in general) naturally slow on Xeons?

    The P4 machine has kernel 2.4.22-1.2188.nptl, while the Xeon machine has kernel-2.4.22-1.2115.nptl. As far as I know, there were no bug fixes relating to speed in the newer kernel.

    Thanks!

    yeah, check smp, and also i've run into a couple of problems with the newer versions of perl being slow. Check the multi-language settings in perl, i know that can cause slow downs.

    Thanks. Yup, it is compiled with smp. Doing a cat /proc/cpuinfo shows 4 cpu's where there are really two.
