MCP78S [GeForce 8200] Ethernet networking very slow with 2 CPUs enabled

[scottmc]

When downloading with firefox, with both core enabled on my AMD Athlon X2 laptop, the download speed crawls along, almost stopping, but if I use pulse to turn one of the off it speeds right up.

[scottmc]

Ran into the same issue, this time when doing a cvs checkout. Downloaded a few files and then stalled. So I turned off one CPU and tried again and it went normal speed.

FWIW, I have 4 cores and no such problem. Maybe this is specific to your network card?

Replying to bga:

FWIW, I have 4 cores and no such problem. Maybe this is specific to your network card?

Quad cores here too, but I wonder:

1. which network card are you using, Scott?
2. does it happens on quad cores systems if only two cores are enabled, whatever the net card?

I'm at office right now, but I'll check point 2 when back home.

seems attachments are still broken, so I'll cut and paste my listdev here for my compaq cq-50-215nr laptop:

I'm not using wireless, but don't see any other network device listed, but the wired network is working since I am writing this on said laptop in Haiku.

I see it now:

fixed summary

[Adek336]

#1667 mentions an Nvidia ethernet controller and slowness.

[Adek336]

#2247 as well.

listdev: ​http://dev.haiku-os.org/attachment/ticket/3260/listdev-mypc.txt

I confirm I have the same on RTL-8139.

[Hubert]

Possible, that this is not the same problem. Sorry.

[scottmc]

Not sure when this got fixed but with hrev30679 I'm seeing normal download speeds even with both cores on my AMDX2 enabled. So this ticket can be closed. Not sure about the other two tickets though.

[mmadia]

closing --> fixed. see previous comments. Thanks for the follow-up, scott!
