I'm guessing its more than seconds slower.... but not really sure how to gage the difference reliably, so as not to be giving flawed information here or have difference due to caching or something.

I'm using firefox 4.X on all home lan machines (that have a gui). Can you recommend some documentation that might help with what you called `Browser tweaking', I've never done anything special to a browser other than add or subtract add-on tools. > * Moving from browser->privoxy to a browser->squid->privoxy setup you > should have seen only a small drop.

No raid, and the hardware of the server is P4 Intel(R) Celeron(R) CPU 3.06GHz and 2GBram running on oldish IDE discs ------- --------- ---=--- --------- -------- Probably should have included some questions about the squid.conf and privoxy/config in the first post. Maybe there are things in there that are not good left as default. I realize that both tools have several config files. I've left all but the two main ones in default state and have posted my working /etc/squid/squid.conf and /etc/privoxy/config There is a lot of debris in the comments but still I thought it might be useful to leave it all in for jogging memories...But also included a way to prune the comments by changing the name of the cgi script at the end of the URL from `disp.cgi' to `strp.cgi'. Any coaching would be well appreciated. ------- --------- ---=--- --------- -------- squid.conf WITH comments: www.jtan.com/~reader/sqcfg/disp.cgi squid.conf WITH OUT comments www.jtan.com/~reader/sqcfg/strp.cgi ================================= privoxy's config WITH comments: www.jtan.com/~reader/prcfg/disp.cgi privoxy's config WITH OUT comments: www.jtan.com/~reader/prcfg/strp.cgi
