 Posted: Fri Aug 11, 2006 5:58 am Post subject: Anyone have any ideas? Excessively slow Ethernet I/O |
 |
|
I have a system here, a new build, which seems to work fine except that
any Network access is EXTREMELY slow. Things that should take 5-10
seconds can take tens of minutes. It's across the board and doesn't
depend on the site being accessed, and connecting other systems to the
same Ethernet cable and connection the other systems don't have the
problem. I was trying to use Windows update to download a 23MB file,
and after an hour it had only downloaded 7 megabytes (on a broadband
connection that routinely sees over 1Gb/sec). I know that MS may be
slow right now ("Patch Tuesday"), but web site access is abnormally slow
also.
This is acting like a bad ethernet port, so I disabled the motherboard
onboard Ethernet port and installed a Linksys PCI Ethernet card.
However that made almost no difference at all.
All other operations on the system seem subjectively fine.
The motherboard is a "Mach Speed" from Tiger Direct (yes, it's a very
low-end bargain board) using a Via P4M800 chipset with an Intel Celeron
D 2.93GHz CPU and 512MB of memory (increasing this to 1GB did not help).
All of the necessary drivers (both chipset and LAN port) are installed.
Anyone have any ideas? |

Try setting the onboard NIC to 100/FULL DUPLEX. If that doesn't help,
try 10/FULL DUPLEX. Are you plugging this into a switch or hub? If
switch, see if you can force the port to 100/FD.

Turns out that the problem was a bad D-Link 5-port network switch. It
wasn't dead ... you could browse the web very, very slowly. But so many
packets were apparently being lost that a large (megabytes) download was
impossible, it would usually fail completely after taking 10 minutes or
so to download a few hundred thousand bytes of the file. Replacing the
switch fixed everything.

Typical failure mode when the on board regulator starts to fail due
to high ESR in the electrolytics.

Not a very likely cause of the problem in a switch with a wall-wart DC
power supply.

Now that is funny. Do you have any idea what goes on after that wall
wart?
