[lug] Samba, VPN, unison & speed

[karl horlen]

sorry i don't have an answer for you.  but i was curious as to what method and or commands you use to determine those 20% and 50% "best" bandwidth utilization figures.  i would like to be able to determine similar types of things if you care to share.

thanks
