I have a
JEE EAR application deployed on 2 clusters (with 2 instances each) in a GlassFish v3.1 application server loadbalanced by an apache server with mod_jk. One of the issues that I am currently facing is that every morning I have almost 100 users accessing the application at 8 am when they start their work and then they access it on a regular basis through the rest of the day. The performance on a normal one person usage scenario is pretty consistent with less than 5 second response time for loading the main page. However, the performance in the mornings when there is a mass hit is pretty bad. Can you advise me on what I can do to improve this?
