Benchmarks for Vapor 1.2.5

About a month ago I launched benchmarks for Server side Swift frameworks. Yesterday I updated my project to the new version of Vapor: 1.2.5. Previous version I used was 1.1.11.

One of the most important updates in Vapor 1.2.x is that Vapor is now using a non-blocking server.

So today I decided to run a new benchmark for my project updated to Vapor 1.2 and results surprised me. It's not only faster than the 1.1.x version, it's now equal to Node.js results!

Vapor vs. Node.js

My server:

  • 2 GB RAM
  • 1 CPU Core
  • SSD
  • 125 MBPS Out
  • Ubuntu 16.10
  • CouchDB

Benchmark from other server was launched as:

wrk -t4 -c20 -d5m https://my_url

API just gets some data from CouchDB and returns it as JSON.

Total requests

Requests per second

Average Latency

These results look much much better than previous, so I'm sure that the backend on Swift can be a good choice. The last question for me is memory usage now. Vapor grew after benchmarks from 13.4 mb to 59.1 mb. Maybe there's some memory leaks in my code, will see.
