Assuming that the boxes aren't otherwise heavily loaded, I wonder about the options used to compile your Perl. For x86 architecture, things like -mcpu=i386 will make a binary that you could run on a steam engine but it won't be able to take advantage of the richer instruction set on newer processors. I don't have a great deal of experience with other modern processors, but from the gcc 3.2.3 documentation: "GCC defaults to `-maix32'" and there's a '-maix64' that may be worth a look, along with the rest of the section ('info gcc' if you have it). Optimisation may also be an issue, but use caution. Many packages (e.g. the Linux kernel sources :) warn against anything more than using -O2 with gcc for example. 73, Ged.
