Varnish is a massive VM to network pipe, nothing 'sophisticated' happens to the data that it deals with.
If that were the case I wonder how well the model would hold up but it does what it does very well and there is as far as I have been able to determine no other program that comes close to the kind of throughput you can achieve with varnish.
