We've just beefed up network buffers (1K->32K), removed
useless devices, added "ccd" pseudo-device, and
increased MAXDSIZ (->512M) and DFLDSIZ (->512M).
This is a Dell PowerEdge 4400 with 0.5GB RAM, and
3 SCSI-3 Seagate disks on a Adaptec aic7899. The NIC
is an Intel Pro 10/100B/100+.
Maybe there's a checklist somewhere about fine-tunning
freeBSD for INN?
We're also runnning a "vmstat" and "ps axlw"
every minute (but there were no incidents since then)
thanks,
