This is known and has been discussed several times. I have added comments to
the TODO file about ideas I have to improve things, but afaik I am the only
one (slowly) working on this so don't expect any sudden changes.

Exactly what I found out yesterday:

Gosh! Those are really terrible numbers. Well I have nothing better to offer
than just roll up your sleeves and get cracking on finding the bottle necks
and improving the code flow. I've mentioned my thoughts on this a few times
already and I believe most of them are now collected in the TODO.
Thanks a lot for the table though, it certainly is an eye-opener that we need
to get this fixed.
I wonder why I get so much higher performance when I do uploads over
localhost. I would expect a gigabit link with really fast roundtrips to get
similar speeds.
