Yes you can scare a 6500 :-) you need a bank of BIG sun boxes
say E10k's and a BIG BIG BIG BIG backup silgo ;-). And also
a lot of fibre patch leads.

Also I certainly know in the 5500 days some ISP's had to
run Dual RSM cards to cope with the load unless using L3
MLS.

This is a bit harder as for the router unless it is very sick or you
have a port set to half instead of full duplex then I would doubt th
router. However if you gave me details of the link size and type
ie ATM/POS/HSSI ect and also the router model.

As for a proxy server I guess run a wget  and time the difference
between going via the proxy and not.

If you suspect that there might be congestion on the path to the
site use mtr to see where the packet loss is.
