No impact. Also, on someone else's suggestion, I've tried using "ping -s 8000" to check for packet loss. This gives me a loss of 0.1% (1 packet in 1000 or 2 in 2300). The only oddity is very large RTT's - up to 3 seconds - whilst an scp is running (14.6msec otherwise). Even when the scp is in "go-slow" mode, the RTT's reported by ping can still be 1-2 seconds. I'm wondering if this is a problem with the NIC or driver. Peter To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
