More benchmarks (larger number of users: 500, 1000, 5000, 10000 , batch size
1), first results are trunk, second are patch.

> Analyse changing the persistence format of GroupImpl
> ----------------------------------------------------
>
> Key: OAK-6225
> URL: https://issues.apache.org/jira/browse/OAK-6225
> Project: Jackrabbit Oak
> Issue Type: Improvement
> Components: core
> Reporter: Alex Parvulescu
> Assignee: Alex Parvulescu
> Fix For: 1.8
>
> Attachments: groupimpl-v0.patch, groupimpl-v1.patch,
> groupimpl-v2.patch
>
>
> As suggested on OAK-3933, I'd like to look into using a different persistence
> format for the GroupImpl members.
> Currently this is saved as a list of child nodes, and I'd like to bench this
> against a tree based approach where each sub child node represents a part of
> the key so it can be used for lookup.
> WIP branch can be found at [0], I merged all the commits so far into a single
> one to reduce the noise.
