Hello David Green,
Although the algorithm may be 20% quicker, there are many
other factors involved with scp transfer speed (network
bandwidth/latency, harddisk speed, etc). A 20% increase in
algorithm performance won't necessarily translate to an
overall 20% increase in scp transfer speeds.
I agree, but the test was carried on a machines where CPU idle time was
around 90% through a dedicated 1 GB network interface directly connected
between the two machine i.e. I tried transferring files across the
cluster nodes using the dedicated cluster interconnects. Using the
normal LAN, the time consumed was so much.
Bottomline is there any way to improve the speed like making use of
