Lukasz Lenart commented on WW-4375:
-----------------------------------
Did you perform any benchmarks on that? Anyway, I'm planing to remodel how
expressions are passed around - instead using simple String I would like to
have a dedicated class which will represents the expression itself, its state
and origins (client input, struts configuration, etc). Thus should allow reduce
security checks
> improve security check performance

> Key: WW-4375
> URL: https://issues.apache.org/jira/browse/WW-4375
> Project: Struts 2
> Issue Type: Improvement
> Affects Versions: 2.3.18
> Reporter: zhouyanming
> Fix For: 2.5
>
>
> currently struts is a little low performance because we must do much security
> check,I think struts should provide two ways for security check,One for
> client inputs and the other for non-inputs.client inputs must use the most
> strict check.and server side expressions could skip most check,it will
> improve performance because most of access is from server side.
