First off 200,000 / day uniques would not require that type of server, so you have no idea what your doing... hence why you brought it.
OK. first claim I didn't really have a popular site. now I still didn't know what i was doing even though such site did exist
lets recap what the site was doing
200,000 * 22 (average page views per visit) = 4400000 page views/day (some more some less but a long stretch of very similar days so lets use that here)
each page view in this case is PHP proxy downloading a remote site. editing all links, javascript, css, to point back to that PHP file and forwarding edited content onto the user. so lets figure a average page has what, 25 embedded files? that seems a bit conservative. that would mean 110000000 PHP hits/day or 1273/second which is VERY conservative because the majority of hits happened during US school hours so closer to 2500-3000 PHP files being loaded/second during school hours
thread TLTR ~900mbit/sec (of that half up / half down) PHP + litespeed | downloading + editing and forwarding pages onto users at ~2500 hits/sec during peak hours on the longest stretch using four 2007 era CPUs / 2gb of ram servers (not counting the 3 700 mbit youtube forwarder servers in these stats as that could have easily been handled by apache used litespeed..because you know why not when it is working so well for everything else and money is flying in) if gweedo is to be believed i obviously had a horrible website idea and lost money on these licenses and just want to sell them to get that back
keep telling yourself that having good ideas gets you ignores
