For me, cygwin 1.7 make rsync usable on Windows. Although hacking with the UTF-8 dll, cygwin 1.5 limited paths (or file names) to 256 characters. This limitation was too much for me since I use it to backup user data that can be longer than this. I've read on cygwin list about performance improvements, but since I could not use 1.5 (without modified dll), I can't compare. And I think that most of people that use (or tried) this solution will agree that passing this 256 char limitation worth, by itself, the Champagne :)

I don't use cygwin directly but cwrsync (update 400, based on 1.7 beta with patches + rsync http://www.itefix.no/i2/node/11649 ). I can say performances are good. In a client (win xp)/server (freenas) setup over 100Mb network it takes less than a minute to do a sync of a 6 GB directory with lots of small files when there is no changes. Of course, if there are changes, the time depends of the amount of changes, so it's difficult to report performance. But I'm happy of this solution.

Hi

Has anybody ever made comparisons about the performance of
cygwin 1.7 compared to 1.5? I believe there were some changes
that should make it faster, but I don't know if they affect rsync too.

Thanks

bye  Fabi
