Retrieval of large documents under MongoDB 3.0.6 and WiredTiger is significantly slower than 3.0.6 running MMAPv1. With the following reproduction on my macbook, I saw the following execution times, running the find() operation twice to account for cold data:
Engine | First find | Second find |
---|---|---|
MMAPv1 | 312ms | 1ms |
WiredTiger | 8140ms | 668ms |
