This was previously a AMD-K7 machine (4.0-STABLE) but has been moved over
to a Intel based machine for the time being while I get a new motherboard
(the K7 motherboard is shot -- the other K7 box runs like a charm.)
Running 4.0-STABLE from Wednesday, April 12th. There are two Macronix PNIC
II's in the machine, one at 10Mbps/Half-Duplex(dc0) and the other at
100Mbps/Full-Duplex(dc1) (both NICs use the dc? driver). On the 100Base-TX
side of things, during any sort of heavy network load I get:
Apr 12 13:00:45 cmdmicro /kernel: dc1: TX underrun -- increasing TX
threshold
Apr 12 13:29:17 cmdmicro /kernel: dc1: TX underrun -- increasing TX
threshold
Apr 12 17:25:50 cmdmicro /kernel: dc1: TX underrun -- increasing TX
threshold
Apr 12 17:25:50 cmdmicro /kernel: dc1: TX underrun -- using store and
forward mode
Apr 12 17:25:50 cmdmicro /kernel: dc1: TX underrun -- using store and
forward mode
Now from what I was reading on the older archives, these messages aren't
all that big a deal if appearing in sparse amounts, however I have a
3.3-STABLE machine with the same make/model of network cards on the same
machine with no such messages popping up (slower speed processor as
well).
On the 3.3-S machine I'm able to sustain 11MB/s transfer rates to and from
the network (it's switched) with no problems, however the 4.0-S machine
barely breaks 8.0MB/s on the same test. I originally had 3c905C-TX's in
the 4.0 box but they ended up shitting oatmeal under heavy network loads
(no big surprise there)
The 4.0-STABLE machine has only been up a few hours now:
8:33PM up 7:43, 3 users, load averages: 0.00, 0.00, 0.00
It should be noted that net.inet.tcp.delayed_ack is at 1 on the 4.0-STABLE
machine and 0 on the 3.3-STABLE (I've recently just set it to 0 to see if
it's made any difference)
Machine specs:
--------------
3.3-STABLE (1999/09/16)
P3-450 / 128MB
1 x LNE100TX v2.0 Macronix PNIC II (mx? driver) @ 10Mbps
1 x LNE100TX v2.0 Macronix PNIC II (mx? driver) @ 100Mbps Full-Duplex
4.0-STABLE (2000/04/12)
P3-550 / 256MB
1 x LNE100TX v2.0 Macronix PNIC II (dc? driver) @ 10Mbps
1 x LNE100TX v2.0 Macronix PNIC II (dc? driver) @ 100Mbps Full-Duplex
100Mbps side of the network is switched (LAN). The "test" was conducted by
xferring a 7GB tarball between the two machines via ftp (see ftp notes
below) Except for processor and ram, these two machines are identical
hardware-wise including BIOS setup/version# (and I do mean identical, all
the hardware except processor and ram are identical make & model right
down to the motherboard revision)
One of the first things I checked was if there was shared PCI irqs, this
is not the case, each device has it's own IRQ. USB is disabled.
* FTP NOTES: tests were conducted with stock ftp client in 4.0-STABLE in
active/PORT mode (not PASSIVE). There seems to be a problem with the stock
ftp client with large file sizes. It reported the 7GB tarball as -11TB
(when I did a ls of the file) and ofcourse messes up the bar graph
display. It also stalls for a second when it reaches the end of the bar
graph, but continues without error. It also doesn't show the correct file
size during transfer (as in total bytes to xfer) but it does xfer the file
properly nevertheless, I tested the tarball afterwards. I checked my own
4.0-STABLE machine at home, the stock ftp client exhibits the same
behavior.
I appriciate _any_ response (good or bad) as I need to get this worked out
as soon as possible (I'd like to replace our 3.3-STABLE machine)
