A neater mechanism needs to be put into the million collection test to extract information from serverStatus, WiredTiger stats and compile that information to figure out stalls and test performance.

The correlation of the stalls with the checkpoint is to be observed, again all the information extractable through the serverStatus. We can potentially use statistics from WiredTiger. We have histograms for operational latency, we can also add the "longest operation until now" statistic which gets reset with the collection. I will have to spend more time understanding how serverStatus gets some of these stats from WiredTiger and if we can use them.
