How do you (not how do I) calculate 95th percentile?

(I did this fast, and, who knows; I could be off my an order or two of 
magnitude)

2^64 is 18,446,744,073,709,551,616 bytes.

100 GE (100,000,000,000 bits/sec) is 12,500,000,000 bytes/sec.

It would take 1,475,739,525 seconds, or 46.79 years for a counter wrap.
