Yes, thats why the T1 is good on some benchmarks I understand. And, if I am not mistaking, also Varnish will be?

Anyway, this article gave me (probably not you guys) an easy-to-understand glimpse of the possible future.

Yeah, but apps need to be aware of this right? I think Varnish is in a better position than the "competition" to take this into account. :)
