Disappointing SiS900 performance - driver issue?

Disappointing SiS900 performance - driver issue?

[Aaron Lehmann]

My new motherboard has an onboard SiS900 ethernet device. I was hoping
to free up a PCI slot by switching from my Intel EEPro100 to it. With
the Intel card I can quite easilly pull 11.5mb/s, but the SiS seems to
max out at 3.5mb/s or so. Is this the fault of the hardware or the
driver?

sis900.c: v1.08.01  9/25/2001
PCI: Assigned IRQ 11 for device 00:03.0
eth0: Realtek RTL8201 PHY transceiver found at address 1.
eth0: Using transceiver found at address 1 as default
eth0: SiS 900 PCI Fast Ethernet at 0xcc00, IRQ 11, 00:d0:09:ea:ea:7e.
...
eth0: Media Link On 100mbps full-duplex

Just a me too:

Though with a little better performance.
ftp with sis900 (laptop) @ 5MB/s (2.4.13)
ftp with 3c905C-TX       @ 12MB/s(2.4.2-2)

Padraig.

My sis630 (incl. the sis900) bases Celeron-633 laptop is much faster (using
a 2.4.16 kernel here):

This the sis900 one as a client over a hub and a switch to a 3c59x - and
the other way round:

Hrm.

I get similar results.

But it doesn't live up to this on HTTP or FTP.

Mine is 630.
