A NIC does take a lot of cycles, but there isn't much on that Web site to back up the somewhat fantastic claims of 1000x performance improvement. 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
