Also, it's not clear whether the cards are cost-effective, because they sell at such a fantastically high price. I've thought for years about implementing a TCP/IP stack in a coprocessor board -- even prototyped a dedicated PPP board. Could never convince myself that I could sell enough of them to break even, though. --Brett Glass At 11:18 PM 5/9/99 -0400, Francisco Reyes wrote: >Just saw an interesting link in slashdot about an ethernet card with >built in TCP stack: >http://www.interprophet.com/demo.html > >The makers of the card claim that in a test VS a regular NIC they were >able to push about twice as much data with about 1/9th the utilization >in the CPU. > >Does a regular NIC card takes so many CPU cycles? > > > >To Unsubscribe: send mail to majordomo@FreeBSD.org >with "unsubscribe freebsd-chat" in the body of the message To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
