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.
