>                 Key: FELIX-4811
>                 URL: https://issues.apache.org/jira/browse/FELIX-4811
>             Project: Felix
>          Issue Type: Improvement
>          Components: Configuration Admin

> The ConfigurationManager#listConfigurations is far from optimal.
> It iterates on all configurations, thereby creating a copy of the properties for each
configuration.   Then, for each configuration, filter#match() is called, which itself create
a case insentive copy of the properties for matching.
> If you have quite a lot of configurations and quite a lof of SCR components, it can be
quite time consuming.
> Attached is a YourKit profile view which shows that 90% of the time is spent into copying
properties for nothing.
