The important factor is the number of files.  Rsync uses up some memory
for every file it looks at in a run.  That's why JW said to break it
up into smaller jobs.

Rsync is optimized for a slow "network" and high speed "disk" access.
If you're doing NFS over a slow network, that looks to rsync as a slow
"disk".  If you can, it's probably better to run rsync directly on
the server.
