As an example, I transfered 1930420 KBytes with rsync between two 2.8 GHz Intel P4 machines over gigabit ethernet and got this: transfer method:ssh rshnfs rsync wall time in sec 130.01 79.77 176.03 74.92 MBit/sec116 189 86201 Mind you, this is no benchmark as I

For situations where it's all new files, using -W would make it a lot more efficient and less CPU intensive. You can ask rsync to be slower with it's built in bandwidth limiting options. On Tue, Apr 22, 2008 at 12:14:02PM +0100, Joao Ferreira wrote: > > On Tue, 2008-04-22 at 12:18 +0200, Fabia

Hello all, I'm experiencing about 20MBit/s on a 100MBit/s ethernet connection when rsync'ing a lager number on _new_ files. I don't have much exeprience with rsync. I'dd just like to know if thi is an acceptable bw usage and what could be the limiting factors... in order to try to increase this s
