Tam Nguyen commented on WW-4790:
--------------------------------
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>
I'm out to try setting this
tempate_update_delay=600000000
I'm suspecting that this causing the CPU to spike.
> struts 2.5.10.1 upgrade cause more frequent garbage collection
