Re: rsync speed

[Julian Pace Ross]

Pushing the file from Windows to Linux over ssh takes around 15 min, with an average speed of ~400Kbps (using --progress). Pulling the same file using the same arguments takes around 45 mins, with an average speed of ~150Kbps. Do you mean pulling it back again from Linux to Windows? Or switching machines and pulling it in the same direction from Windows to Linux? I'm going to assume the former. Yep its the former... pushing and pulling from the same Windows PC which is a P4. The linux server is a PIII....i delete the 350MB file from the source/dest in turn in order to try it... It seems slow to me (ssh overhead??) This depends on how slow (or loaded) your CPU is. For instance, on an old Pentium III 733mhz, the encrypting that ssh does cuts down the top transfer speed compared to an unencrypted daemon connection (I think the ssh connection was about 33% of the daemon connection, IIRC). Both CPUs reach a max of 2-3%, so the bottleneck is somewhere else... If you're backing-up over a local network, it may well be safe enough to dropp the ssh transport of your daemon-style transfers and just run a password-protected daemon on your Linux box. I know, but I'm trying to simulate transfer over an internet conncetion on my lan first. I'll experiment further and let you know what I come up with... but I'm quite sure its something particular to my setup. Thanks wayne! Julian
