I've checked the same file on *different* server, but it has very similar
hardware (not Dell, but also Dual Xeon 2.8, SCSI, 2GB ram, etc...).
It was on FreeBSD 4.10.

# time tar -xf mysql-m.tgz
0.244u 33.724s 4:25.26 12.8%    374+291k 14216+1828io 8pf+0w

During this test server was loaded (load averange about 1.00, Apache, MySQL
running). I wasn't able to turn deamons off but I suspect this result
could be much better than it was.

So is my problem only FreeBSD5 releated? Seems to be.
