Our system:
P90
40Mb RAM
Conner fast/wide drive
Buslogic PCI fast/wide controller
3C509 ISA nic
Linux 1.2.13, Netatalk 1.3.3
Used for: Netatalk + Samba ( + light misc. UNIX services)
Tests today done on almost-idle network, PM6100/60 as client.
Copying a large Netscape Cache folder (average file size 7.1 Kbytes):
to Netatalk server: 4.6 Kbytes/second
to Mac : 5.8 Kbytes/second
Copying a single large tar file (18,680 Kbytes):
to Netatalk server: 242.6 Kbytes/second
to Mac : 233.5 Kbytes/second
In our installation, Netatalk performs very adequately for storing user
data files, and for running applications from the server when when the app
loads completely at startup. Applications which constantly refer back to
the server are uncomfortably slow.

PS--Are these figures in-line with what others are seeing?
