Last time I checked the gzip source had no assembler optimisation for systems 
other than i386.  So if your 3.2GHz machine (which obviously would be a P4 at 
least not an i386) is running the AMD64 instruction set then you could 
probably improve performance by running the 32bit binary.

A compression algorithm that is more complex (slower) than the gzip algorithm 
but which is implemented in 64bit assembler might compare well with the 
current gzip performance for modern machines.
