Significant performance degradation in creating managed users with external DJ as repo

When compared IDM 7.0.0 performance with IDM 6.5.0.3, noticed about 13% degradation in throughput and 16% in mean response times when creating managed users with POST(see similar degradation with PUT), we have the following between 6.5.0.3 and 7.0.0

           mean response times(ms)       throughput
6.5.0.3:   56                             532
7.0.0:     65                             462

This should be the cause of performance degradation in other features such as recon(9%) and livesync(19%) from DJ to IDM when external DJ is used as repo.

To test using pyforge:

1. Use the config file attached
2. run the command below:

run-pybot.py -v -c perf -s simple_managed_user.CreateManUsersPost OpenIDM
