I've been running a ton of benchmarks the last 3 weeks for the Tomcat Performance book with Remy. General questions like that are very hard to answer. Most performance issues are the result of bad design and poor administration.
If some one is telling you "tomcat can't perform." they need to back it up with numbers. I'm assuming this is for an existing site, so you should have some web access logs to look at. If you're asking, "Can tomcat handle 1000 requests/second?" I would say it depends on the hardware, setup and the page. If it's a static page, then I would say depends on the hardware. But here's the catch. How many of those requests are for images? and how many page views does that equal? I can gaurantee that unless your Yahoo who gets 1.5billion page views a day, you're not going to get 1000 page views a second. Based on the recent presentation at PHPCon by a yahoo staff member, their average pageview per second per machine is around 4. They also have 4500 servers, so again be specific about what kinds of apps, the response threshold and peak loads. I know there are some major sites using Tomcat, though many aren't allowed to acknowledge publicly. I hope that helps. by the way, most of the benchmarks out there comparing performance of servlet containers are flawed and synthetic. In my own test with tomcat 4.1.12 with Orion's old jsp test page, Tomcat was faster than orion 1.5.3. It's very easy to write test pages that makes one server appear faster than another. peter lin --- "Anecito, Anthony (HQP)" <[EMAIL PROTECTED]> wrote: > Hi All, > > I am looking at Tomcat for production and seeing > some things that make me > question its use for production.
