Does anyone know from where can I get more information on how many user request a tomcat could handle at the same time in other words I've to do capacity planning for tomcat, I am new with Tomcat. I've two webapps running on my current apache installation. my one webapp requires about 1 GB of RAM and other 512 MB. I am not sure the memory requirements of Apache Tomcat. but my system has 1.5 GB of RAM all together. Do you think it can handle about 500 user requests simultaneously with reasonable performance? Thanks in advance for your response.
I would say that if one of your apps *requires* 1GB of RAM, and the other one *requires* 512MB, and you have 1.5GB RAM total on the box, then no server, never mind just Tomcat, will be able to serve your applications, never mind 500 users.
