Did you do this between EVERY step below? > After creating a file of 1GB I copy it with the standard rsync command. > Then I made "touch -t 200901261330 test.xyz" and run this command: > rsync -av --bwlimit=10000 --stats --progress --delete > 192.168.222.82:"/home/test" /backup/rsync0 > It takes about 80sec. > Then I made "touch test.xyz" and run the rsync command with forced md5: > rsync -acv --bwlimit=10000 --stats --progress --delete > 192.168.222.82:"/home/test" /backup/rsync0 > Now it takes only about 45sec. Create the file, flush the cache. Copy it with rsync, flush the cache. touch the file, flush the cache. etc. ---------------------------------------------------------------- YES, the same results! The copy command takes nearly twice as long as the -c command!:( I can't explain it!!! With the copy command I get following result: ================================ receiving incremental file list test/test.xyz 1048576000 100% 15.86MB/s 0:01:03 (xfer#1, to-check=0/2) Number of files: 2 Number of files transferred: 1 Total file size: 1048576000 bytes Total transferred file size: 1048576000 bytes Literal data: 0 bytes Matched data: 1048576000 bytes File list size: 45 File list generation time: 0.013 seconds File list transfer time: 0.000 seconds Total bytes sent: 226747 Total bytes received: 129657 sent 226747 bytes received 129657 bytes 3581.95 bytes/sec total size is 1048576000 speedup is 2942.10 And with the -c command: ================== receiving incremental file list Number of files: 2 Number of files transferred: 0 Total file size: 1048576000 bytes Total transferred file size: 0 bytes Literal data: 0 bytes Matched data: 0 bytes File list size: 61 File list generation time: 0.009 seconds File list transfer time: 0.000 seconds Total bytes sent: 15 Total bytes received: 85 sent 15 bytes received 85 bytes 1.77 bytes/sec total size is 1048576000 speedup is 10485760.00 A question: In the copy command above, I get after receiving the incremental file list a transfer rate of 15.86MB/s. Is this the speed testing the checksums? Because I set the bwlimit to 10000. Or am I wrong? _______________________________________________________________________ NUR NOCH BIS 31.01.!
