Actually, it's right there in your varnishstat output:
36189916 476.66 250.71 Client connections accepted
404804204 5494.13 2804.30 Client requests received
Your request:connection ratio is > 10:1! This is a very good situation to
be in. varnish doesn't have to spawn nearly as many threads as it would if
the ratio were lower, as is common at many other sites.

It's probably inaccurate to assume that things will scale linearly :)
