Re: RAM usage for AFP

We run a lab of Macs for our students at our school.  Unfortunately,
logging in and starting Word has been slow when we are packed (50
computers).  Looking into it I found that much of AFP's memory was in
virtual memory.  So we purchased 4 GB more RAM (we are now at 6 GB).
However, still the fact remains that more than double the memory is
in virtual memory (usually 275 MBish in Real Memory, and 650 MB in
virtual memory).  With 3 GBs free!  I have already followed AFP548's
article on increasing the thread count, but that didn't seem to
affect the memory.  What can I do to have AFP use more of the
available memory?

MS Office simply does not
play nice with network user homes. If you haven't yet, remove the DoFonts
app from the MS Office directory and remove the MD fonts form the ~/ Library
folders. You may also consider checking out NHR

or working out your own scripts to do something similar.

Basically the questions boils down to whether or not we should get a new Xeon server for our students. I am struggling with the decision because the 2.0 GHz G5 (10.4.11) that we are running only reports around 30% usage. Would the Xeon server help with the situation, or is the Network Home Redirector the way to go (probably it is regardless of what server I am using).


I witnessed at one location, a marked, significant improvement in AFP performance, when migrating AFP file-services from a G5 running the PPC build of 10.4.9 server,
to an Intel Xeon Xserve running 10.4.x (10 out of the box, IIRC) - namely the Universal Binary build. The difference may come down to the improvements in the new (UB) build,
as mentioned by Nigel Kersten in his afp548 article

part 1 is here

Thereafter, I helped migrate another location to the UB build of 10.4 server on their G5 Xserve and they also saw some performance problems go away entirely.

Having said that, probably your biggest issue right now is the performance hit incurred by Office with network homes as mentioned by Jeff.
I say - certainly start with NHR
