Benchmarks When running tests, installing operating systems, and compiling software for my Ultra 5, I came to the stunning realization that hey, this system is 64-bit, and all of the operating systems I installed on this Ultra 5 (can) run in 64-bit mode.

gunzip performance

Just a thought regarding the unzipping performance. They are likely to be even (32 vs 64) because the unzipping process is a very low-CPU process. The algorithm is designed to make the decompression much easier than the compression, and therefore you are limited by I/O. You didn't mention whether you wrote the decompressed output to disk or to /dev/null. Of course, making that change would only remove one part of the I/O, reading the compressed file would still be done.
Thanks for the interesting article.
