The short version. Copying over SFTP to our centos boxes maxes out at 2MB a sec. The Question: Is there some sort of speed limitation somewhere in the ssh/sftp daemon? Does anyone have any idea why this could be happening? The long version We have centos 4.6 installed on 2 different machines, different hardware, different nics. Even on 2 different subnets. I've tried different switches, 1000 Full/Half 100 Full/Half and still get the same speed. It maxes out at 2MB a sec. Same switch, network, client using sftp to our xserves gets 10MB a sec. Basically filling the pipe of the network. The only thing that is the same on both the linux boxes is the distro. So i thought maybe someone may have come across this before. I haven't tried other protocols yet (FTP and HTTP) I'll check that tomorrow. Thanks, Jamie
