---------------------------------------------------------

thank you so much for responding.

I'm not familiar with using a profiler to check, but it seems to effect every state of our app. this is our  config properties.

 
struts.ui.theme=simple
struts.multipart.parser=jakarta-stream
struts.multipart.maxSize=20971520
struts.url.includeParams=none
struts.ognl.allowStaticMethodAccess=true
struts.ognl.enableExpressionCache=false
struts.serve.static=true

we used all most of the standard strut tags <s:checkbox, <s:property> 

do you see any setting that I'm not setting that could cause the GC and CPU to spike ?

I'm out to try setting this

tempate_update_delay=600000000
I'm suspecting that this causing the CPU to spike.

> 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.

> spring 3.29

> any insight would be helpful.
