Hey folks.
I have a PII-400 machine running Solaris x86 2.6 which is using the dnet0 interface (built in interface on the motherboard) for the mounts. The mount that is giving us some problems is off of a f630 running 4.3.4D5 over gigabit. The PII has a 10/100 interface (adaptec I believe).
The behavior I am seeing is as follows:
- large file ops (like cat /dev/zero > foo) are bursty - iostat shows the filer 100% busy but the filer is not breaking a sweat.
The stats:

I was just wondering if anybody else had seen this sort of behavior on their end. I suspect this is hardware on my end (cable, card, etc) but swapping has not helped.
Thanks.
