My solution is to lower the dirty_ratio and the dirty_background_ratio to prevent the kernel from pumping all the data into memory. Just exec: echo 0 > /proc/sys/vm/dirty_background_ratio echo 0 > /proc/sys/vm/dirty_ratio and afterwards sysctl -p (if you have those 2 params defined in sysctl.conf) and everything will copy like a charm :) I have faced similiar problems when copying my vm’s around.

When I use putty's pscp versus the copssh scp the difference is rather remarkable. pscp tops out at 100k/s give or take. copssh's versions goes to the mega range rather easily if the pipe can make it. copssh is a direct port of the latest OpenSSH code and recommned to anyone doing anything from windows with SCP/SSH. It is command line though. Speeds in SCP in windows vary greatly depending on who’s code base your using.

I do not use SCP or WINSCP or any of those tools anymore. I use FileZilla (FTP Client) and do a quick connection to port 22. The speeds that I get using SFTP are more than 3x what I get using SCP.

Is there any way I could get on your beta group for it? Hey, I read your post about using cacti for URL monitoring (webseer). Is there any way I could get on your beta group for it?

I'll be glad to beta test (in a vm of course) when its ready. Glad to hear your going to upgrade cactiEZ to 5.x soon. I’ll be glad to beta test (in a vm of course) when its ready.
