Not that it answer's your question directly but just offer the perspective that http://weblog.textdrive.com/article/73/sencers-caching-plugin-for- textpattern-is-snazzy PHP-MySQL based textpattern is "fast" at ~30 req/sec on a single CPU'ed server. And if we put the 35-38 req/sec in the context of how much you're serving. Let's say that text+javascript+images+?? = 125 kilobytes per page, and let's assume that you're app is serving 30 req/second. 30req/sec x 125kb page = 3,750 kb/sec = 3.75 MB/sec => 3.75 MB/sec x 60 sec/minute x 60minutes/hour x 24 hours/day = 324,000 MB/day = 324 GB/day So 30 req/sec is 324 GB of network bandwidth out per day; in a 30 day month it's 9720 GBs or 9.72 TBs or 30Mbps constant. Is that at about where you'll be? Is this one mongrel process you're talking about? Now that's also a different issue from being "much quicker for users", that's page latency not req/second throughput. - Jason _______________________________________________ Mongrel-users mailing list Mongrel-users@rubyforge.org http://rubyforge.org/mailman/listinfo/mongrel-users
