Default Scp and SFTP speed much difference???

we have CENTOS 5.X on server A and Server B. Both servers have Gigabit network card connect to same switch.

I test network speed from Server A to Server B and found speed much difference:

SFTP: 42 MB/Sec

SCP: 20 MB/sec

SCP command: scp -Crp -o CompressionLevel=1 user1@ServerB:/TMP/File1 .

Anyone know how to improve SCP speed?

don't specify compression on gigE, it will just slow you down.

scp/sftp should be virtually the same speed, all else being equal
