Description of problem:
I have onboard realtek NIC:
00:12.0 Ethernet controller: Realtek Semiconductor Co., Ltd. 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:  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):
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
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!
