Running mongo-perf test Update.MmsIncShallow1 and the other mms tests shows a large regression (~90%) from master to 3.0.4. On evergreen, 3.1.5 gets 1100 ops/s and 3.0.4 gets 11,434.
The following data captures both runs. The first run (A to B) is with 3.0.4. The second run (C to D) is with 3.1.5.
In particular, there appears to be a lot of eviction traffic in the second case, but not the first. The test is 5 seconds long and the server was started immediately before the test.
