For a project my company is working on we have transactions requirements of 1600 transactions per second. The transactions consists of processing a servlet in Tomcat, doing a database call and then displaying the results to the user so the effective number of transactions Tomcat has to process is actually greater than 1600. Can Tomcat cope with 1600 requests in a second(a 4 processor Sunfire machine will be used)? Based upon our current application architecture(our java application has tomcat running inside it), 1600 request per second means we may have 1600 threads open simultaneously. 2. From one article I read at linux journal, Tomcat 3 didn't scale very well with multiple processors because of JVM issues. -- To unsubscribe, e-mail: For additional commands, e-mail:
