Here's a more useful output, with having set the number of files to 6000, so that it has a dataset which is larger than the amount of RAM.
--($ ~)-- time sudo ksh zfs-cache-test.ksh zfs create rpool/zfscachetest Creating data file set (6000 files of 8192000 bytes) under /rpool/zfscachetest ... Done! zfs unmount rpool/zfscachetest zfs mount rpool/zfscachetest Doing initial (unmount/mount) 'cpio -o > /dev/null' 96000493 Blöcke real 8m44.82s user 0m46.85s sys 2m15.01s Doing second 'cpio -o > /dev/null' 96000493 Blöcke real 29m15.81s user 0m45.31s sys 3m2.36s Feel free to clean up with 'zfs destroy rpool/zfscachetest'. real 48m40.890s user 1m47.192s sys 8m2.165s Still on S10 U7 Sparc M4000. So I'm now inline with the other results - the 2nd run is WAY slower. 4x as slow.
