The other processes within the server are. Note that, in order to show off their board's performance, the makers of the card had to run raw data transfers -- no processing done on the data at all. The moment you add something like Web service, Sendmail, or whatever, the limiting factor is no longer the IP stack, if it ever was. (And whether it EVER was still depends on a number of factors. I could imagine a TCP/IP card being SLOWER than a dumb NIC, or even dropping connections, if it ran short on memory.) --Brett Glass At 10:41 PM 5/9/99 -0700, Amancio Hasty wrote: >The scenario is a plausible given that windows is so ineficient 8) > > > > > > On 10-May-99 Francisco Reyes wrote: > > > Any ideas what happened to that NIC? > > > It is my impression that chips that offload functions from the CPU seem > > > to be gaining some momentum.
