Massive mongodb performance improvements
Before: very low throughput, bad scalability in number of aggregates and number of events, full CPU load consumed by mongod process due to inefficient event fetching
Now: much improved throughput (> factor 10), good scalability, moderate CPU load
All tests are green (run with mongo 2.0.24 driver).
