I mean that ssh transfering at speeds of 1.21M/s seems a bit low on a lan if you mean over an internet connection that is a good speed up from an ok one.

I will do my own tests and see what i get. I expect higher amounts using an older version of ssh on my network. jdub how come you were getting only these -
gutsy: 183824384 bytes transferred in 559 seconds (320.9K/s)

hardy: 183824384 bytes transferred in 145 seconds (1.21M/s)
-amounts.
on a lan…..

Might be worth re-running some tests with the standard packages. Hopefully this might also fix some of the real problems I've had at home across a LAN transferring huge files (eg: 4.7 gig ISO's of a certain linux distro we're all familiar with), where it gets between 1-2 gig into the file and then gets timeouts.

But in general file-transer-protocols that use UDP are a little bit faster than TCP. Off course SSH is more than just file-transfers. Esspecially the shell stuff sort of requires serialized communications. All I meant was that I _thought_ the fact that SSH transfer were slow was _because_ of that. Not that using UDP would be a smart thing for SSH. I just assumed it had something to do with that. I was wrong. @Satya
