[NTLUG:Discuss] Network question

[Brian]

A few days I posted a question as to why the network speed between two
Linux boxes linked via two 10BaseT nics (one PCI, one ISA) was so
abysmal (on the order of 1 or 2 Kbps).  Someone suggested upgrading from
2.2.12 to 2.2.14.  Rates were still abysmal, but in only one direction. 
Further investigation/reading led me to some Becker docs which said
something about the ISA bus not being able to pull received packets from
nic buffer fast enough to keep up with incoming packets.

Is it possible for a PCI nic to "flood" an ISA nic?  Would it be worth
my time to replace the ISA nic with a PCI nic?

FWIW, I discovered if I set the mtu on the PCI nic to 256, and the
txqueuelen to 6, I could "put" to the ISA nic at a rate of about 540
Kbps.  This seemed to the peak rate I could achieve by tweaking these
two parameters.
