Hi.. I apologize for reviving this post, but this problem is really hitting me hard. I have an interactive fiction site (www.friedfiction.com) that has been experiencing some terrible response times over the past month. After investigating, it appears that my app is cold starting almost every two minutes. If someone is filling out a form or reading a story, and they've been idle for more than two minutes -- they have to wait approx 10-20 seconds for the app to cold start before it can process their request. This is giving my site a bad reputation.
- What is your application ID? friedfic - How do you know it is being cycled out? You'll need to insert some code that only gets called when the app cold starts. Logging the servlet init - How much time of inactivity does it take before your application is cycled out? Every 2 minutes - What time or days does this seem to happen? All the time - What frameworks or libraries are you loading?
