--pf9I7BMVVzbSWLtt Content-Type: text/plain; charset=us-ascii Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Transferring files from my desktop to my laptop with rsync (over a point-to-point netowork connection) is extremely slow, maxing out at around 50 kB/s and often dropping to 0. Both systems show hardly any activity. Is this normal for rsync running over a network? There is a rsync daemon running on the laptop. Network interface on the laptop is xl(4), the desktop is rl(4). I think that the link is OK, because transferring dumps with nc from the laptop to the desktop can max out the connection (9000-10000 kB/s over 100baseTX full-duplex). However, when I try nc to transfer a file from the desktop to the laptop it is extremely slow, topping out at around 200 kB/s. When I check with netstat, the qeues on the laptop are empty, while the send-queue on the desktop shows a large value: Active Internet connections Proto Recv-Q Send-Q Local Address Foreign Address (state) tcp4 0 40951 192.168.0.1.55460 rfs.65000 ESTABLIS= HED I've tried disabling the firewall on the desktop (laptop doesn't have one) and enabling polling on both interfaces. It doesn't seem to make any difference. Are there any bottlenecks I could check for? Or is this just a case of crappy hardware? The rl(4) based cards don't seem to have a very good reputation. I've got an old 3com 905B card lying around. Would it help if I used that instead?
