I did several 1-collection and 1000-collection runs on build 7.0.0-4554. I noticed the running time of 1000-collection runs is much longer. I compared the runs with old runs on build 7.0.0-3874 and found the running time of load phase is longer in recent runs. Note that, this issue didn't happen in 1-collection run.
