As well, we all know that there are 28 DS1's in a DS3 >(that's a T3 to you and me).

On a machine *that* big??? The main thing limiting ftp.freebsd.org is the *memory*, and then the CPU power is a fairly close second.... There are nice solutions to that memory and CPU problem without going SMP... If memory wasn't a limiting factor -- I would guess that 400+ connections would be reasonable on a P5-100 using a *BSD* type OS... I have heard that with a new (reasonable cost) upgrade, ftp.freebsd.org will be serving between 500-1000 FTP users soon. With the new technology coming out and using a single processor -- if cost wasn't very important -- I would *guess* that the BSD solution might be scalable to approx 1500-2000 FTP users with the server connected directly to a T3. Perhaps more with some magic... But some of the *BSD*'s are coming out with SMP anyway... John dyson@freebsd.org
