After a lot of tests on Solaris ZFS/NFS performance, i came into this (time tar -xpvzf pam-1.2-MRSL.tar.gz):

real    0m7.867s
user    0m0.050s
sys     0m0.060s

The pam-1.2-MRSL package is 515K in size, with just 89 files on it!

Running against a Linux NFS server (XFS filesystem):

real    0m0.637s
user    0m0.050s
sys     0m0.080s

After the reading of this, i was “obligated” to try it… and:

real    0m0.530s
user    0m0.070s
sys     0m0.070s

Ok, i did read “ZFS: The Lumberjack” by Neil Perrin, this entry by Eric Kustarz, this by Rock Bourbonnais, and the “ZFS Evil tuning guide”… but.. what did you do?
