Thanks so much for the replies. (And on the weekend, no less)
The clients boot up now, but it takes almost 10 times longer than before
on the other switch. Performance seems fine once they've booted. There
are a lot of messages throughout the bootup process saying "nfs server
not responding" followed by "nfs server OK". It eventually gets there,
but I can't really function with bootup times this long. One thing I
noticed is that it said that it had only negotiated 100BaseT, half
duplex. Could that be causing the slowdown? I told the switch to auto
negotiate, but to default to full duplex 100, should I force it to full
100?
Any further tweaks I can try to speed up the boot times?
