[p4] Off-site Perforce performance/optimization

We are running P4P with no variables, so it's running in it's default
state (which assumes compression if I understand correctly).

The RSYNC idea is interesting.

Do you think the best way to do it would be to have a proxy setup here
for this project and then use rsync to update the offsite proxy's cache
from the on-site proxy's cache?

Has anyone ever tested this?

I'll second what Steve Vance said about making sure the server -> proxy
transfers are compressed.

p4p queries the server on every request that doesn't specify a
particular file revision, to find out which version to serve.
For small files this can be slower than transferring the files directly.
The minimum size of files to cache is tunable on
2005.2 and later p4p, using  the -e flag.
