I did some more investigation. Increasing the buffer sizes above 65535 did not seem to improve performance further, although at 262144 it wouldn't work at all (just get a message about no buffer space being available).

It also didn't perform as well as fetch on the same download. With fetch I was able to achieve over 90kbyte/sec downloads consistently, not bad for a service which claims to have a maximum thruput of only 400kbits/sec... - Mike To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
