packets sent to a router are typically processed differently and with
different priority then packets forwarded through it. This makes
traceroute fairly unreliable.
I measure acceptable performance on the basis of the needs of my
applications. In general I need <= 100ms rtt and little or no
re-ordering to the counterstrike hl2 servers I play on. providers that
can't deliver that reliably don't get my business.
