Glad you've got it going. Performance depends on the particular version
of rsync, options used, network, dasd, dasd interface (nfs, samba, direct
(SCSI (version), IDE, FC)), Operating systems, memory, processors, other
load, network traffic....
I actually get pretty cruddy results with rsync in my application, which
involves mirroring a NAS device containing roughly 2M files in 102Mb, over
a wan, using solaris to run rsync, forced, by a flaw in the NAS nfs unlink
implementation which reorders unlinks, to use NFS2, which exposes the
solaris mtime bug. If I try to do it all, it takes about 2 days to grow
to around 3Gb in memory, then crashes (there's plenty left over), so i
can't do the whole thing in one swipe, which means hard links are not
propogated, and deletions can be orphaned by the list generator (the
script i use to break the jobs into chunks rsync can handle).
People running against directly-attached dasd, or fast DFS, and doing
reasonable-sized jobs, get really good speeds, and great efficiency.
I've had to write my own replacement, which is about to go into
production, but I still love rsync. Within its limitations, it's a
superior tool.

Dear Mr.Tim,
Thank you very much for your valuable suggestions.
Now I am able to mirror the set of files from one system to another
system which are on the net.
Yesterday, I calculated it is mirroring 188MB file in 63 sec from one side to another
side.
Good performance. Is anywhere the performance about rsync is mentioned
in terms of file size / time.
I am going to use this rsync command in script continously to mirror the
two systems always.
Once again thanks,
regards,
laks

I just played back your mail in my head, and realized that you mentioned
the rsync server. I read your command, from which it was plain that you
were NOT trying to contact a rsync server, and gave instructions based on
that. In case you were trying to contact a rsync server (rsyncd), I
suggest you read the man pages for both rsync and rsyncd.conf. the rsync
manpage explains how to invoke rsync to have it be a server, and the
rsyncd.conf manpage explains how to set up the required configuration
file. The rsync manpage also explains how to invoke rsync to CALL a
server (as opposed to starting a temporary process via an external
transport to act as your remote server, as your commandline showed).
Direct consultation of the documentation which Tridge, Martin, Dave, and
everybody else has put so much work into, can cover the broad
possibilities with much less latency than an email list.

Ok: You're using an external transport (rsh, unless you've defined
RSYNC_RSH as something else(probably ssh)). First thing to check is
whether you can rsh to destinationmachine. See what happens if you do
"rsh destinationmachine uname -a". Does this report back the information
for destinationmachine, or does it give you "Permission denied". If so,
get rsh working. From your error, I'm certain this is the problem, as if
it were a permission problem on a file or directory, you'd get an error
more like this
