[p4] Performance of remote perforce depots and proxies

[Chuck Karish]

Pay attention to the "-e" command line option for p4p.  The proxy seems
to do well at reducing bandwidth requirements for transferring large files.
For small files the overhead for checking metadata to find out whether
the cached versions are up to date can be problematic, and it's most
problematic over high-latency links.  Apparently p4p isn't as parsimonious
as it might be with these queries.
