Description

since we upgraded our struts version from 2.1.18 to 2.5.10.1, our app has been doing a lot of garbage collection, CPU are up more 30%-40%. We have 2 application that yield same results after the upgrade. Stress test has almost double the time in performance. these are the tech stack of our apps.

struts 2.5.10.1
spring 3.29
tiles 3

any insight would be helpful.
Thank you
