I ran a few performance tests comparing ver 1.1.0 and 1.2.1 on the
enrichment topology using the
[load_tool](https://github.com/apache/metron/blob/master/metron-contrib/metron-performance/README.md).
The EPS numbers for 1.2.1 are seen to be on-par or better than 1.1.0. However,
I noticed that the Avg CPU usage is higher on 1.2.1 (about 70%) as compared to
1.1.0 (about 40%). ---
