Multi-Threaded SSH/SCP

Posted by kdawson on 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."

    Wally: "My proposed work plan for the year is to stress-test our product under severe network conditions. I will accomplish this by downloading large image files from the busiest servers on the net."

    Crowds were shocked to discover that multi-threaded software runs faster on a multi-core system, it was hard to contain the excitement over the discovery which could revolutionise software development!
