    Is there a client out there that supports this? I'm hitting a wall using sftp/ftp(ssl) at 10/25 mbytes per sec, a bit too slow..

    Forklift only seems to max out at 100% over 8 cores (2009 Mac Pro) rather than say 800%. Same with Fetch, etc.

    Any ideas?

    Is that transfer speed? If so, wouldn't that be governed by your available bandwidth?

    And are you connecting to a server on your own network or on a different network? What is that server's max upload rate?

    The server I'm connecting to is on 2 gigabit while mine is on just gigabit. Both are on my own network. Both servers can easily do more that 100mb/s. It's just the ftp client...is slowing it down..

    Your hard drive will also be the bottleneck here. 25MB/s doesn't sound too bad to be honest.

    The array does 750/650 read/write easily..I'm pretty sure it's the ftp client that's limiting how fast it can go :(

    Ah didn't know you had a RAID setup.

    What kind of speeds do you get if you copy a file via sharing in Finder..?

    94 mb/s to another gigabit connected Mac Pro.

    From this article, it seems that the standard ssh protocol has some issues with latencies on high speed connections. Maybe you can try to compile the patched OpenSSH package on your client and/or server.

    And one more question - what happens if you run two or more sftp sessions in parallel? How does the total download speed change?

    Hmm interesting..I'll have to pass this on to the people that manage the Dell server. I didn't get a chance to try running parallel sessions however I did try increasing the max connections to the server which resulted in the same speed.
