Mysql & PHP connection/Performance

My company is looking to setup this server/database intensive website which will consist of probably over 1,000 connections and operations (select and update/insert) each second. We're talking to investors and they want to know how the heck are we planning on making sure the server doesn't crush under the pressure. The only thing I could think to say is that a site that we're modeling ourselves after is using Perl which is slower than php and they have no problem, and they have probably 2,000 operations per second. But they want hard information, does anyone on this list have any hard information? -- Thomas Deliduka IT Manager -------------------- New Eve Media 5629 Westlake Drive Galloway, OH 43119-8498 Phone: 614-870-3098 Fax: 614-870-7486 Mobile: 614-537-6445
