limited bandwidth with SiS900 onboard NIC

From: Thomas Latzelsberger
Date: Fri Jun 18 2004 - 11:16:29 EST

Dear readers,

As mentioned on http://teg.homeunix.org/sis900.html and http://www.latzinator.com/acer_aspire_1705SMi.html there is a problem with bandwidth for the SiS900 onboard NIC. I allways use vanilla kernels and I'm having had this problem from 2.4.22 to 2.4.24 and from 2.6.2 to 2.6.6.
The symptom is easy to explain. I connect the PC to a 100MBit switch and no matter which method of transfer (ftp, scp, samba, nfs) I use, I get a maximum transfer rate of less than 400kB/s. By accident I found a dirty workaround that might be a hint for some tech savvy hackers: if I force the NIC to use halfduplex (allthough it's connected to a switch) it works like expected (7-8 MB/s).

The only help I can be is that I can test new kernel drivers and send you feedback.

Any help highly appreciated,

Thomas Latzelsberger

FYI:

about the Linux I use:
gentoo with vanilla kernel. no additional kernel patches.

hardware:
Acer Aspire 1705SMi, I run the P4 without HT (thus, no SMP related issue)
