Thanks for the suggestions. I agree lots of stuff can only be decided after putting into a specific environment. But still, any number that can be shared?
How many concurrent users your Tomcat can serve? Thanks again! Li On 12/24/06, Gary Evesson <[EMAIL PROTECTED]> wrote:
Generally in a production environment, increasing the number of threads from the default is compulsory. You need to balance that against the amount of memory that you have allocated for your JVM, which needs to be balanced against the amount of memory available in the machine. Handling concurrent users generally comes back to the number of connections that your architecture can handle and how much work your database server(s) (assuming you have some) can handle. Our experience has been that these things become an issue before tomcat does. It depends on your application *a lot*. Nothing beats real load testing to figure out where *your* stress points are. They are probably going to be different to other people...

Actually you can imagine the server serves a site like mySpace where people can access their own home, blog, images, forum, etc. I know it is still not easy to answer, but I'm not looking for an answer to my specific question. I'm just looking for any similiar experience that can be shared and hoping I can learn some. Another question, how many threads do you think Tomcat can have on one machine? And will increasing number of threads help processing more requests? I think 100-150 per server per second is not a good number. But if it is true, does that mean Tomcat is not suitable for large website? And what does commercial products like WebLogic can normally do? Well, lots of question at my end. Thanks for sharing of your idea. Any thing will help. Best!
