Xapian works on 64-bit systems (I find the idea that you need to "port"
code to 64-bit systems a bit odd...)

My current dev box is x86_64 linux.

I've not actually done any benchmarking.  Large search systems will tend
to be I/O bound, so having a wider bus is good, but a 64 bit chip
running in 32 bit mode might be as fast as in 64 bit mode (assuming
the memory accesses work the same way).  I don't think it's obvious
without testing which will do better anyway.

If you do some benchmarks, I'd be interested to hear how they compare.
