RTL-8139/8139C/8139C+ (rev 10) Subsystem: Sony Corporation: Unknown device 80ea Flags: bus master, medium devsel, latency 32, IRQ 3 I/O ports at b000 [size=256] Memory at e5800000 (32-bit, non-prefetchable) [size=256] Capabilities: [50] Power Management version 2 The driver is 8139too. Network performance is slow - I am getting 24Mb/s on 100Mb network. When I was running RH8 on the same machine, I was getting over 90Mb/s. On a different machine (3Com card) I am also getting over 90Mb/s, so I believe it's a Fedora+Realtek combination. I am up to the latest revisions for all packages. I measured NFS, scp and netcat speed, the numbers were consistent. Version-Release number of selected component (if applicable): kernel-2.6.11-1.1191_FC4 How reproducible: Always Steps to Reproduce: 1. scp remote_machine:remote file . in 1 window 2. run iftop in another window and watch the speed of the transfer Additional info:
Have you tried the 8139cp driver? Devices that can work w/ the 8139cp driver should perform much better than using the same device w/ the 8139too driver. You can change "8139too" to "8139cp" in /etc/modprobe.conf in order to try it. Please do so and report the results. Thanks!
