Speed problem

Mermgfurt ! I have some problem with syncing two machines which are connected over a Gigabit-connection. I'm trying to use rsync with ssh because of the authorisation mechanisms (keys). It starts quite ok with 18 MB/s (this small speed may have something to do with our internal net) and falls

I don't have a system with ssh available to check with (believe it or not, it's not approved for our network), but i think the sshd_config or ssh_config might be able to specify using compression as a default. Is ssh on the sending side, perchance, using a lot of CPU? I don't know of any cpu

Regular Expression support

2002-11-11 Thread Paul Faure
I have added regular expression support using a POSIX implementation. The patch (against 2.5.5) is attached. The implementation is simple and follows the same mechanism that is implemented for normal searches. I added these command line arguments: --rexclude=PATTERN exclude files matching

weak checksum question

2002-11-11 Thread Jeff Abrahamson
The weak checksum in checksum.c (see snippet below) differs substantially from the one discussed in Andrew Tridgell's doctoral thesis on rsync and elsewhere that I've been able to find. I didn't find discussion of the change in the mailing list archives. Well, so I'm curious what the benefit of

You haven't really provided enough data to even guess what is limiting your performance. How similar is the directory tree on the target (receiving) machine? There are three general possibilities: - It's empty. - It's present, and substantially similar to the sending end. - It's
