Philippe Mouawad commented on OFBIZ-4268:
-----------------------------------------
Hello,
Thank you for your very rapid response.
I propose to implement the following:
- I will just lazy build the Map once it is requested but till then I will use
ResourceBundle, so this will not change the behaviour, It will make us gain CPU
+ Memory when methods not using map will be accessed.
My first tests seem OK but we plan a full UTA so if I submit this patch be
confident It will work.
Regards
Philippe

> Project: OFBiz
> Issue Type: Improvement
> Components: framework
> Affects Versions: SVN trunk
> Reporter: Philippe Mouawad
> Labels: MEMORY, PERFORMANCE
>
> Hello,
> We are working on performance improvements while load testing the
> application, and I noticed that ResourceBundleMapWrapper uses arounbd 140 Ko
> per Serving thread, in our configuration with around 1000 thread, this is a
> big memory impact.
> I started investigating the class and code seems strange to me, in fact I
> don't understand why InternalRbmWrapper constructor copies creates a Map by
> copying content of ResourceBundle.
> Why not only have a reference and delegate calls to the ResourceBundle ?
> Furthermore since put methods throw RuntimeException, I really don't see any
> case where the Map will change.
> I made a test removing this code and delegating to resourceBundle and it
> seems OK.
> If someone knows why it was made like that I would really be interested, if
> there is no reason I will submit a patch
> Thank you
> Regards
