Hi, For the past day I've been trying to set up file synchronization between two Windows 2000 servers using rsync 2.6.6 (distributed in cwRsync package - http://www.itefix.no). Unfortunately I've encountered a major showstopper - rsync on the server machine makes System process to consume about 90% of CPU time. In addition (or as a result), rsync performance is significantly worse that I would expect. Is it a known problem? Is anybody else having it too? What steps do I need to take to resolve it? Thanks in advance. -- Misha Bergal MetaCommunications Engineering

In addition (or alternately), if you're using an encrypted transport (such as ssh), try switching it to a faster cipher (e.g. "-e ssh -c arcfour") or use an unencrypted transport (such as rsh or a direct rsync daemon setup). ..wayne..
