updatinator benchmarking (Was: rsync benchmarking)

Alexander,

I should mention that doing better than rsync with a custom solution
is not unexpected. rsync tries to be fairly general purpose, and
special purpose delta tools can almost always do better, as they can
take advantage of more information about the data.

At least rsync provides a harder target to beat than scp or ftp would,
so its useful in that way :-)

One thing to watch is round trips. Large numbers of http GET requests
means lots of round trips. rsync uses very few round trips, so it
tends to do well on high latency links.

Cheers, Tridge
