Performance:
workstation 2.4 Ghz P4, 512 MB RAM, SATA disk
over 100 Mbps Ethernet
to server 2.4 Ghz P4, 2 GB RAM, IDE/SCSI disk array
~800000 files / 992387 links (lots of hard links)
~20 GB / 28330052 kB (multiple storage of hard links)
time: 4h33m
~ 60 files / sec.
~ 1700 kB / sec
cpu usage was negligible.
bandwidth limited by network for large files.
top files/sec was much higher than average (> 300).
conclusion: bottleneck were seek times for DA.
(hardly optimizable except maybe by sorting inode numbers)
