After migrating my pet project from Vapor 1 to Vapor 2 I've run benchmarks to compare performance. I didn't run benchmarks for the last version of Vapor 1.x which is 1.5.15 so I will compare Vapor 2.1.0 to results of Vapor 1.2.5 that I have from my last results.
My server:
- 2 GB RAM
- 1 CPU Core
- SSD
- 125 MBPS Out
- Ubuntu 16.04.2 LTS
- CouchDB
Benchmark from other server was launched as:
wrk -t4 -c20 -d5m https://my_urlAPI just gets some data from CouchDB and returns it as JSON. Vapor project has been compiled with Swift 3.1.1.

Vapor 2 is about 14-15% faster than Vapor 1.2.5. And what's important - Vapor 1.2.5 memory usage grew up after benchmarks from 13.4 mb to 59.1 mb and Vapor 2 started with just 3.6 mb and its memory usage grew up to 5.3 mb. That's very impressive.
