Rsync speed over network.

Haile the list ;-) I am new to this list and this is my first post so grretings to all and nice to meet you. I am setting up rsync here to do a MASSIVE copy from one machine to the other. I am moving mail servers so I must copy /var/spool/mail/ over to the other machine. I understand and

On Mon, 11 Nov 2002, I've been saying: But why does it only happen with rsync ? Ok, the last tests with rsync/rsh have shown the following: (all on the receiving side) CPU: 100% Load: 2.5 blocks in: 38000/s even though nothing get written (no statistics) when it starts to write, it goes from

Hi all I just ran these tests on my network and came up with these results. I found it interesting and thought I would share. In all test the same 2.5 Gig logfile was used for transfer (2719312019 Nov 12 11:42 maillog.back) (2.5G Nov 12 11:42 maillog.back) The transfer was done over two Gigabit

Ok, now I found something. When the effect of heavy speed drop occurs, it doesn't seem to send much bytes anymore. Block-in rate on the receiving side drops dramatically from 31000/s to 5000/every 4-8 seconds (which results to a rate of nearly 1 MB/s, that's what I got in the end). CPU load goes

One thing to add: When this problem shows up, it seems rsync tries to get all the CPU time on the sending side: 93-98%. Even ssh can only get between 2 and 5% of CPU time. Even though rsync is not growing in memory, top shows nevertheless that it really gets almost every second of CPU time. What

Heya ! It seems that we found it out. It's the partial flag. We tested a lot of stuff here with strace and could see that after some while there came timeouts on some descriptors (0 = stdin). We saw that after those timeouts got heavy the blocks-in-out dropped heavily. But the reason wasn't clear

Thank you!

Dear rsync developers/contributors, I've been using rsync either directly or indirectly via unison etc. for quite a while now. Thanks for the great software and algorithm! cheers, prabhu -- To unsubscribe or change options: http://lists.samba.org/mailman/listinfo/rsync Before posting, read:
