What do u think it's going wrong here? any hints, suggestion >flames? one thing you have to consider is that modems, t1s, dsl, etc,etc are measured in bits-per-second, whereas most transfers are bytes per second. and there are 8 bits in a byte. so on a 256kbs dsl line you should get 256 / 8 = 32KB/s . . so, thats sounds about right. note that a little "b" means bits, and a capital "B" means bytes. --- doug reynolds | the maverick | mav@wastegate.net PGP Public Key Fingerprint: 6E7B 9993 B503 6D45 E33A 2019 26E5 C1DB To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
