Joel Richard resolved SLING-4589.
---------------------------------
Resolution: Won't Fix
> Performance: Read properties lazily in MergedValueMap
> -----------------------------------------------------
>
> Key: SLING-4589
> URL: https://issues.apache.org/jira/browse/SLING-4589
> Project: Sling
> Issue Type: Improvement
> Components: ResourceResolver
> Affects Versions: Resource Merger 1.2.8
> Reporter: Joel Richard
> Labels: performance
> Attachments: SLING-4589.txt
>
>
> About 4% of the rendering time is spent in MergedValueMap in
> ValueMapDecorator.putAll because the JcrPropertyMap has to be read fully
> before it can be added. Therefore, I would suggest to lazily read the
> properties in get(key) and merge them there.
> By the way, in my case 202 of 252 times the MergedValueMap is created only
> with a single value map.
