11pt;font-family: Calibri;">years ago, we ran sflow p2p stats on a
slower machine with spindle disks. On freebsd + ufs, the disk seek iops
rate was around 60-70% of the spindle capacity. On linux + ext3, the
disks were pegged at 100% with similar filesystem parameters (noatime).
We didn't do a whole lot more diagnostics at the time, and later moved
the configuration to a faster machine + SSDs, but the general conclusion
we came to was that without filesystem tuning (which we didn't really
want to do), freebsd's out-of-the-box performance was measurably better
for this sort of workload.<br><br>Nick<br><br><blockquote style="border:
