What are the real-world transfer speeds you are seeing with rsync SuSEbox-to-SuSEbox over a 100TX network? As files get larger, the backup/transfer times keep rising. I am seeing transfer rates for gigabyte size files of 11.04 MB/s over the network. A comparison to drive-to-drive transfers within the same 10.3 box are about 28 MB/s. I wouldn't expect box-to-box transfers to be the same as drive-to-drive transfers, but losing 60% seems large. That maybe normal, but I thought I would ask and see what others are seeing.

100Mb Ethernet has a Theoratical Max speed of 12.5MB/s. If you are getting 11+, then you are doing fine. If you wnet with Gigabit, you would be limited by the speed of the drives most likely because Gigabit has a 125MB/s Theoratical transfer rate.

Not quite. There's also overhead, such as the various headers & CRC that take some of that bandwidth. The ethernet switch may also limit bandwidth. -- Use OpenOffice.org http://www.openoffice.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
