True, I did take that into account. I could be mistaken but I think the main
problem lies with the proxy software. I think that Polipo and, especially,
Privoxy are pretty resource intensive, and affect performance more than Tor
itself.
Polipo has been shown to be faster than most browsers

Polipo has been shown to be faster than most browsers' implementation of

As for resources consumed, people are running Polipo on embedded routers

The main reason why Tor currently has bad performance is that it

circuits) under the same TLS(TCP) connection. This is very important
from the security perspective, but causes problems when any link in the
