I stand corrected :-) . I had thought Olaf had indicated that DMA wasn't ever used, but good to hear it is.

Checking network buffer sizes sounds like a good idea. I have no idea where one might find these though!

Sorry for the late comeback, the SAM was unplugged for a while because we moved into a new house. I've installed MUI-OWB and it is definitely faster browsing that OWB so yes, the slow performance was due to the software only. Thanks for your inputs.

Download speed: 21.51Mbps
Upload speed: 0.359Mbps.

Receiving constantly strangely low upload speeds...MK

Back to normal at 7Mbps download and 0.9Mbps upload with MUI-OWB

@acmn
That's weird you get so bad upload compared to your downstream.

I've added

Code: Select all

iprequests=128
writerequests=128
copymode=fast
to DEVS:NetInterfaces/RTL8139 and set following environment variables:

Code: Select all

SetEnv SAVE Roadshow/tcp/do_timestamps 0
SetEnv SAVE Roadshow/tcp/do_win_scale 0
SetEnv SAVE Roadshow/tcp/mssdflt 1460
SetEnv SAVE Roadshow/tcp/recvspace 65536
SetEnv SAVE Roadshow/tcp/use_mssdflt_for_remote 0
Take a look at SYS:Documentation/Roadshow/RoadshowControl.doc first and try without the SAVE switch.
