>             Project: Jackrabbit Oak
>          Issue Type: Bug
>          Components: mongomk
>    Affects Versions: 0.15
>         Environment: Centos 6x64

> We were creating some data for a performance test and we noticed that our script took significantly longer to run with mongomk than with crx2.
> The scenario we are running looks like this:
> 1.) Create x users, x groups and x resources.
> 2.) Add set of n users to a group #n and then add an access control entry for that group to resource #n. So group 1 will have only user 1 in it and will be assigned to resource 1. Group 10 will have users 1 - 10 in it and will be assigned to resource 10.
> What we found was that it took significantly longer to perform this action with mongomk than it did using crx2.
> For the record both tests were performed on indentical systems (CentOS6x64 with 16gb ram) running load15, using either the crx3mongo, or crx2 run modes.
> The scenario wasn't designed as a performance test, we were just bulk creating test data, I just happened to print out the time with each update and noticed that they were very different between crx3mongo and crx2.
