I have a ISA-based 50 MHz i486 box connected to a 166 MHz UDB (Multia)
via 2 metres of 10Base2 coax. Nothing else is connected to this network
(apart from cable terminators).

The i486 box has an Allied Telesyn AT1500 ethernet card (ISA); the UDB
has a 21040 PCI ethernet interface. The i486 box runs Debian 1.1;
the Multia runs NT3.51 (I haven't put Linux on it yet).

If I transfer large files (> 300 Kbytes) using ftp from either box, I
get a throughput of about 100 kbyte/s, plus or minus 20%.

This is less than 10% of the raw bit rate available (10Mbits/s)
on the coax.

Considering that the AT1500 can send/receive packets back-to-back, and
that there are only two hosts on the network, I would have expected a
higher throughput.

Am I getting reasonable performance for the hardware I have? Are there
no-cost ways of increasing this performance? (Apart from putting Linux
on the UDB, of course.)

What kind of ftp throughput do other people get?

Thanks,

Alan
