Ftping big file over my 10M network now about 15% slower with ethernet harvesting turning on. Mark, please get slow machine (say 100MHz or slower) and test you fu^H^Hboring harvester on it before committing anything. The whole devrandom affair gone too far and shown exactly how things should not be developed in FreeBSD. -Maxim To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
