> I see possibility to optimize VpeNodeInvocationHandler - method invoke - there are a lot of calculations behind the method.
> for example in case if the object type is String - you call ElService.replaceElAndResources - which perform a lot of complex string analyze operations.
> to speedup calculations - there is a sense to save calculated value and return calculated results during subsequent function calls.
> ordinary you and third party creators call this function often.
> so this simple pre save strategy will speedup page rendering process.
