The card that I think is causing the problem is a Racal NI6510 which is a
NE2100 clone (uses the nele driver).  The other card is a 3Com 3C509B (ep
driver).  I'm using 10BaseT links.  The NetBSD version didn't change, but I
did compile a new kernel (with all the PCI bus stuff etc.).  Actually, I
did compile MROUTING into the kernel for the first time, could that be
causing performance problems?  The only other software thing that changed
is that I upgraded the version of ipfilter to 3.2.10, but I did that a few
days before the hardware upgrade and people didn't start complaining until
JUST after the hardware upgrade.  The only other services that run on the
box are named, sendmail, imapd, samba, and apache, but all of those are
barely used at all (just my e-mail, the occasional DNS lookup, and the
occasional connection to the HTTP server for netscape Roaming Profile
stuff).  The 386 was running all those services too (although MUCH slower).

Any of this sound like it could be causing a problem?  Thor told me that
ISA DMA on PCI machines gets a low priority and is probably what's causing
the slowdown.  I plan on picking up a few PCI network cards sometime soon -
hopefully that'll fix the problem.

Thanks!
