My understanding of the internals of Perl would suggest that it's
quite good at thrashing the cache (since it compiles to a parse tree
and then interprets that tree) and might not benefit too much from
having loads of registers.

My take on OSes and hardware is that you should make the most
appropriate match:

SPARC: Solaris
x86: Debian
m68k: whatever it came with (AmigaOS or MacOS 7 in the case of my pile)

... so if there is a requirement for Solaris (ick), I'd get a Sun box.

I'm not sure you can really describe PHP as a thin layer over the top
of libc. PHP is what Microsoft would invent if they were trying to
clone Perl.
