Tor+Privoxy: slow is an understatement

On suggestion of a member of this forum, I’ve been trying to make my internet browsing more secure by adopting the Tor/Privoxy combo. I’ve set them up as per the instructions on the Tor site, but browsing is awfully slow. And when I say “awfully” I mean it: a 56k modem would be faster.
Is this normal? Is there any way to speed it up? Where am I going wrong?

proxy browsing is usually slower than normal browsing

edit : wow…i didnt see the date on that :doh:
