Re: Replication speeds?
Obviously looking at more iostat information would give a better idea, but I'd estimate that you are NOT I/O bound. Sorry I can't give you absolute numbers from UM, but I can share a patch that we wrote that we believe has increase sync throughput substantially, as evidenced by the lack of a sync backlog which we were getting before we added the patch. The patch itself is pretty simple. As with most TCP-based request- response protocols, the Cyrus sync protocol suffers from artificial "Nagle" delays. See: http://en.wikipedia.org/wiki/Nagle's_algorithm for what's good about Nagle's algorithm. The patch disables Nagle delays in both sync_client and sync_server. :wes nodelay.diff Description: Binary data On 09 May 2007, at 11:05, Nik Conwell wrote: What sort of rates are you all getting for replication?

So it is auxprop _or_ saslauthd. You have to check imapd.conf first.
