It's possible that heavy interrupt activity from your IDE disk and/or
CD is causing serial interrupts to be missed. If you are low on RAM,
netscape will cause more paging and thus more disk activity than the
lighter lynx.

It happened to me where heavy CD activity really screwed PPP throughput.

Try the following:

# hdparm -u 1 /dev/hda
# hdparm -u 1 /dev/hdb

and /dev/hdc and /dev/hdd if you have them as well. This tells the IDE
drivers to allow other interrupts in while handling disk and CD interrupts.

Later,
Kenn
