Re: rsync very slow, but not a network issue

Reini (and Steven), Okay, I get. This benchmark you introduced below compares rsync on two variables: copy speed locally vs over the network, and copy speed for copies onto indentical target files vs different target files. And your benchmark showed that rsync was faster for copies onto

Hello all, Thanks for the help so far, on this issue with the mysterious non-network based rsync slowdown. To recap... Brian Dessent wrote: Reini Urban wrote: Alexis Gallagher wrote: When the file is alredy there, rsync reports a speedup of about 70. (When the file is not already there, the speed

rsync very slow, but not a network issue

Hello, I am finding that rsync+ssh is giving extremely slow file transfers. But this slowdown is hitting not when it needs to send data over the network, but when it applies the rsync algorithm which is supposed to be faster than sending all the data over the network. This is very puzzling.
