Now, the app is being used by larger groups and in higher numbers. So I put it on in Windows 64 bit, using the new JDK 7 64 bit release and Tomcat 64, all on a server class machine. I specified max memory to be 3500 MB. A recent load test showed that searches are a problem. When a user runs a search and retrieves 1000 records, after several users doing this several times, the JVM runs out of memory. I estimate it takes a retrieval of a total of 500,000 records (adding up each user's queries) before the server runs out of memory... I tried the new garbage collector by specifying in Tomcat's Java options -XX:+UseG1GC but this seems to have little effect. Any suggestions would be appreciated. thx.
