Multi-Threaded SSH/SCP

Posted by kdawson on Tuesday February 12, 2008 @10:19PM from the recovering-wasted-bandwidth dept.

neo writes "Chris Rapier has presented a paper describing how to dramatically increase the speed of SCP networks. It appears that because SCP relies on a single thread in SSH, the crypto can sometimes be the bottleneck instead of the wire speed. Their new implementation (HPN-SSH) takes advantage of multi-threaded capable systems dramatically increasing the speed of securely copying files. They are currently looking for potential users with very high bandwidth to test the upper limits of the system."

Pretty sad it takes someone to 'discover' a fix for such an issue.

This sort of thing should've been coded in from the start (is it in rsync?).

i/o / cpu decoupling is known issue with known and simple solutions (although linux doesn't make it as easy as it could).
