I've tried irqtune and played a bit with the PPP/chat
asyncmap, but my PPP download speed is erratic and I'm
loosing packets. The upload is near perfect, 2.5-3 k/sec,
but the download sucks. 0.5 - 1 k/sec most of the time if
I ftp a file.
I've seen this being reported here before, but couldn't
find anything in dejanews.
