I think you have jdk update too. If so we have faced some how same performance
issue.
We switch from `jdk 1.8` to `jdk 21` on the version `6.7.0` ( We do not changed
struts version and only upgrade jdk) . The performance of application drops by
this upgrade. Both the cpu and memory usages increased. Even the simple jsp
pages take long time to download.
I have not done any profiling yet. But it may its is because of jdk upgrade.
( which of course I don't know why )
I have make an issue at [https://github.com/orphan-oss/ognl/issues/347] too as
it may be OGNL issue

> After upgrading to version 7.0.0, the JSP rendering time has significantly
> increased from around 500ms to approximately 1.5 seconds. Upon further
> investigation, it was discovered that the increase in time is primarily due
> to Ognl.getValue taking longer than it did in the previous version.
