ok, i retested because i wasn't sure if i had tested on both sides...
i had tested with only the reverse proxy on for sure.
now i tested again and the slowdown comes from using the proxy in the
client machine. if i leave it on and disconnect the reverse proxy i
still get the slow speed like i have with both proxies on.
still, it goes from 1 second to 4 seconds to transfer a webpage which
kind of sucks :P

i guess that is normal then. sorry for the fuss.
