Thanks Bob, interesting link & suggestion, but it came too late -- I read your message on Mike's computer at Mike's store, and left with an Intel PRO/100 S NIC.
Now this is so cool - the JPGs in Mozilla pop up like they would be in cache (but they aren't), and scp is twice(!) as fast as what I had under win98 with the old NIC for my 70MB download test, and w/o a single error or collision: xyz.sql.zip 100% |**************************| 69311 KB 05:31 - Horst (still with some academic Qs below) On Wed, 18 Dec 2002, Bob Miller wrote: > Here's somebody on the web who had a very similar problem, with a > similar solution. > > http://msgs.securepoint.com/cgi-bin/get/netfilter-0211/37/1.html > > I wonder if your cable modem is using a larger MTU than ethernet has, Does MTU mean mess(age) transfer unit ? Hhm, though largely acadimic now, if I had to multiplex(*?*) my end users on an about 1GHz bandwidth, larger packets would make sense ((I assumed multiplexing, or is it truly broadband with each end user having their own ~0.5MHz bandwidth at a fixed frequency? --the latter assuring QoS (including for those users that are not using, thus little overall flexibility)) > and is repacketizing your TCP stream along the way.

Hhm, there may be a reason ATT highly recommends a 10/100 NIC although they *average* delivered bandwidth is much below that... > > Just for a grin, before you shell out for a new NIC, why not try a > different release, such as KNOPPIX?
