[OpenAFS] Slow writes with OpenAFS 1.2.8

[Joao Pedro Barreto]

I have been experiencing extremely slow writes when I use my AFS system. 
  For example, writing 700MB of files to a AFS volume takes about 80 
minutes to conclude. I've tried to do this with both a Windows 2K client 
and a Linux client, and the results were similar.
In contrast, writing the same ammount of data to a WinNT file server on 
the same local network takes typically less than 10 minutes!

Is this a known issue of OpenAFS or of the particular version of OpenAFS 
I'm using (1.2.8)? How can I optimize my servers write performance?

Thank you in advance for your help.

Some additional details:
I have two PentiumII server machines (333Mhz with 128MB RAM and 2GB disc 
each) running Debian Linux 2.4.18-bf2.4.
I have installed openafs-1.2.8 from its source code and set up an AFS 
cell comprising the two server machines, connected to the clients 
through a 100Mbps LAN.
