Description Zenith88 2011-10-31 18:23:49 UTC
Description of problem: Driver initializes the gigabit adapter in 100 mbit mode

Version-Release number of selected component (if applicable):

Linux host1 2.6.35.14-96.fc14.x86_64 #3 SMP PREEMPT Fri Sep 16 13:55:02 EDT 2011 x86_64 x86_64 x86_64 GNU/Linux

How reproducible: Always

Steps to Reproduce:
1. Boot into Linux - network xfer speed won't exceed 1000-1900 kb/s
2. Boot into Windows - xfer speed will reach 60 Mb/s

At this point in the F14 lifecycle, we are only fixing security bugs.  You might try the soon to be released F16 and see if your performance is improved.

Comment 2 Zenith88 2011-10-31 18:52:24 UTC
You may just as well replace 14 with 15 or 16, just look at the kernel version.
This has nothing whatsoever to do with Fedora distribution version.

Yeah.  It says 2.6.35.14-96.fc14, which is old.  F15 is 2.6.40 (3.0), and F16 is 3.1.  So... the kernel versions are different.  Unless you're suggesting you've tried the latest kernel and still found performance to be lacking.  If so, you should contact the upstream driver maintainers on the netdev list.

Comment 4 Zenith88 2011-10-31 19:14:19 UTC
This is a core problem with the driver itself which is included w/o changes into all kernels since it was introduced.
I am contacting the driver maintainer for years since he wrote the driver to no avail.
The only way to address this problem is in the distro - please stop including this faulty driver! Someone else will fill the vacuum once the users will complain. Otherwise ineptness of this miserable excuse for a developer will be forever ignored.

Comment 5 Josh Boyer 2011-10-31 19:35:44 UTC
Sorry, but from a distro standpoint allowing people to use their hardware even if it is slow trumps not letting them use it at all.  We aren't going to turn off the driver in Fedora.

You might try both sets of maintainers upstream again:

Realtek linux nic maintainers <nic_swsd> (maintainer:8169 10/100/1000...)
Francois Romieu <romieu.com> (maintainer:8169 10/100/1000...)
