single file, correct.. about 350 megs for example.. i'm running in the background: netstat -I en0 1
i also was keeping an eye on my cpu monitor, thinking that might be the bottleneck, but i'm not using more than around 15% cpu during hte copy, so that shouldn't be it (not to mention it's a dual core system and the other core is idle). is there some debugging parameters i could try to get to the bottom of this? what are some of the other parameters that could affect xfer speed ? in all honesty, i didn't expect full scp-like speeds (is that even how sshfs file system syscalls, or is it an sftp-like interface in the background, or maybe a 'cat' on the remote server for opening a file heh). i figure there would be some overhead, but this doesn't seem right, and i guess it's only my system that this problem happens on (i also tried another client host, same server, and got 80-90% of the scp speeds there). thanks.. and if you have those implementation details, i'm interested in those too :) On May 14, 6:21 pm, Amit Singh <[EMAIL PROTECTED]> wrote: > What are you transferring: a single large file? a few large files? > lots of small files? a mixture of both?
