hpn-ssh High-Performance-enabled ssh

scp

scp -oNoneSwitch=yes -oNoneEnabled=yes

rsync -av -e ssh 45-tangle2/*0025.bin ljdursi@nuexport00.cita.utoronto.ca:/mnt/raid-cita/ljdursi/athDrape/45-tangle2

If the files compress well, compressing first, or transmitting with compression on (scp -C, rsync -z) can significantly enhance effective data transfer rates

with hpn-ssh rsync -av: ~70MB/s scp: ~50MB/s

without: about half that.

Numbers << less than that: could be a number of things.

 - network connection between scinet and your machine
 - how busy is the server
 - how busy is the disk
