The original got mangled a bit... Ftp.cdrom.com usually runs at about 300 users max -- but if it was only supporting FTP it would be able to handle more (and is turned-up once-in-a-while.) The major limiting factor is that the system is only a 100MHz triton chipset motherboard with 128MB of ram -- and of course only 64MB of it is cached, (big 80MB mirror scripts run fairly often!!!) There is an effort in progress that should be able to support many more users on that site soon... John dyson@freebsd.org
