I want to set to false attribute unpackWARs in Tomcat host configuration file.
Does running unpacked WAR affects an application performance?
We run a setup like this for one of our applications. No real performance problems other than the Java overhead to begin with. Just be careful about dynamic files, they tend to be a pain when you keep it all packed together since WAR files and dynamic files don't work well together.
Overall nothing on my end. Our application is a Supply Chain Management system, runs on a web server with a DB backend, accessed 20 hours a day from suppliers around the world, average user load is 20-30 per hour with lots of updates and requests.
