More than 1h per 10GB (3h for 25GB) on a Gigabit lan. Meaning of course that
only a small part of this size are really transfered.
I've already seen a single account with more than 1.000.000 emails for less
than 2Gig taking 3 hours, rsync have really difficult to handle so many files
at once !
It should not take that long, the problem is with rsync is it needs to
read every file you want to transfer, then read the same on its own
server, then do the deletes, and then transfer (or other way around if
you use --delete-after) I suspect it might be a disk issue, what are
you reading from and to? scsci? any raid?
true :), but do you use it on both? remembering as I said above it
needs to "read" on rysnc server as well, writes are, well the timing
difference between them is really not to much to be bothered about, so
if your rsync server uses ext2/3 thats fine for writes, but youll have
the severe performance hit on its "read".
and what FS do you use (ext2|3/reiser/etc...)?
reiserfs, on ext3 such big directory is really not a good idea :)
Whats the command you are using for rsync?
(please, I know you wont, but I'll ask anyway because you'd be surprised
how many people do, but dont include any username or pass stuff, we dont
need to known your rsync username or your secrets file-name :) )
