 Description   

This is the same replica set as in SERVER-16482. The performance on rc4 (community) was measurably degraded from 2.6.6. The suspected root cause of that is still under investigation as SERVER-16065.

We upgraded to rc5 (enterprise) regardless. Unfortunately, rc5 (enterprise) displayed a severe degradation over rc4 (community). Please see MMS charts below - note large spike in queues, decrease in opcounters.

Will follow up with logs shortly.

We are pleased to confirm that, as of 3.0.0-rc6, we now have increased throughput on the newest version of MongoDB!
