Hello Paul, Have you tried dedicating memory to the JVM, if you're running the Virtual servers on an x86 Operating system, it doesn't use more than 4GB memory so to fully utilize the server's memory, you need to run tomcat x64 install version Regards, Olayemi Olatunji -----Original Message----- From: Paul, Subhro [mailto:subhro.p...@pseg.com] Sent: Thursday, February 12, 2015 1:19 PM To: 'users@tomcat.apache.org' Subject: Help required to calculate Apache Tomcat resource Dear Team, I am an application developer from TCS and working for PSEG (https://www.pseg.com). We are using Apache Tomcat6 as application server for the website. Two virtual servers are configured for this and each one of the servers had 2 CPUs and 4 GB RAM until 26 JAN 2015 when both Tomcat servers crashed. So we added some resources to the virtual servers (Now it is 8CPUs and 8GB RAM each box) and increased maxThread parameter of tomcat from default (which is 200) to 300 and restarted Tomcat servers. OS of the systems are Linux6.5 . We need to know what the relationship between thread and memory is. If N numbers of requests coming to the server how many threads can process that and how much memory is required for that. Actually we are targeting to increase the maxThread count upto 500 but we need to calculate that, to process this much of threads what will be the best Hardware configuration? Please let us know if any more information is required for the same.
