Hey.
I'm having some problems since i updated from kernel 2.4.24 to 2.4.25 .. it
seems that 2.4.25 has some real performance problems.
The problem is that i can't get the NIC's to work fine.. i don't know why,
i've already used several kernel configurations..
i've also tried with patch2.4.25pre4 and... nothin' ...even used another
switch 10/100mbit.. not even with patch-2.4.26pre2 it goes normal,
I've compiled the kernel in another computer, with too many different
configurations, different hardware.. etc.. and the result is the same.
Some friends of mine are having the same problem.
Well.. with kernel 2.4.24 i usually had a max speed of 12Mb/s .. now , with
2.4.25 it only goes to 2,2Mb/s MAX speed. :(
I've tried to use vsftpd, proftpd, apache 1.3.x, apache 2.x, samba.. etc
etc.. with kernel 2.4.24 works pretty fine... but since 2.4.25.. wow..
Not even with the patches 2.4.25rcX it worked.. and.. i don't know what more
to do.
Here you have some information:
Computer 1:
Pentium 3 @ 733Mhz
Board with SIS Chipset.
NIC's: SIS900 & Realtek 8139
....
OS: Slackware 9.0
Computer 2:
AMD XP 2600+
Board ASUS A7V8X-MX Chipset VIA KT400
NIC's: VIA Rhine
....
OS: Slackware 9.1
----------
None of this computers works OK with kernel 2.4.25.. well.. the problem is
that with apache... proftpd.. vsftpd... i only can get speeds of ~2,4Mb/s
MAX! .. i've tried to change cables.. switch.. etc.. nothin'.. i boot to
kernel 2.4.24 and everything went normal.

If you're only seeing 12Mbit/s (b=bit, B=byte) already before
then there's something at play here with your network I'm afraid.
Replace the nics and you'll see the problems should go away.
I haven't seen any problems so far with my equipment.

Start by getting it up to 100Mbit on the old kernel and then ask
for more help as 12Mbit/s points to other problems.

I'm assuming you meant MBytes/s, and assuming you're timing large file
transfers, where disk speed could be a limiting factor. 12 MB/s is 96Mbit/s,
which sounds about right for Ethernet. Hard drive transfer rates are usually
20-40. But without DMA, in my experience, it can fall to around 2 MB/s,
which is about what you're getting.
The dmesg from the first machine says DMA is on, but the second machine's
dmesg doesn't mention it. The following info, for both machines and all
drives, would be helpful:
hdparm /dev/hdx
hdparm -t /dev/hdx
And if you notice DMA is 0, you might try
hdparm -d 1 /dev/hdx
But be careful. It's entirely possible that DMA got disabled because it was a
risk on your drive or chipset.

Most probably he meant 12 _megabytes_/s, == 100Mbit/s.
As to 2.4.25 problems, maybe it's just a duplex mismatch.
Use attached program to collect more statistics
(CPU/network load etc).
In case you aren't able to compile it (it was compiled with dietlibc),
I attached static binary executable too.

Suggestion: take a look at the changelog for 2.4.25 and see what changes
could have effect on your network performance.
For example, I had problems with my 3Com card in 2.6.4-mm1, but no on
2.6.3-mm1, so looking at the changelog I saw changes made into 3c59x.c.
Reverting one of those changes fixed my problem.
