Depending on the how many CPUs it has and what not, the E4500 may not be
much faster, or may even be slower. but it should be rock solid reliable,
the E seris are nearly bulletproof hardware.

None really. You may as well set --enable-integer-datetimes when
compiling since there should be no great performance penalty for running
64 bit values for datetime.

Other than that, no great difference. note that being on 64 bit hardware
means you can likely have much more shared buffer memory than on X86
hardware, where you're limited to ~2 gig.

Mostly the OS. I know RedHat had dropped their Sparc line, but there is a
project out there (can't recall the name, but you can google for it) that
'ports' RedHat's releases to Sparc hardware.

Debian maintains a Sparc port if you want to use debian.
