My ZFS test shows performance improvement running on AMD64, but not for Intel EM64T nor UltraSparc-IIe.
Refer to this previously-mentioned chart for microbenchmarks on various BSWAP*, BE*, and LE* macros: http://dan.drydog.com/reviews/6729208-bswap3-opt-chart.png I reran my ZFS test with these changes: * non-forking find: find . -exec ls -l {} \+ >/dev/null * imported ZFS pool to swapfs (/tmp) before running test to avoid disk I/O variation * ran find in a loop 20 times (discarded first 2 results) All times (real, user, sys), in seconds.
