Figured I should link to the 2.4.9 annoucement from this old thread (as it
shows up high in google).
In 2.4.9 we did quite some improvements, annoucement here:
http://akka.io/news/2016/08/19/akka-2.4.9-released.html
<http://akka.io/news/2016/08/19/akka-2.4.9-released.html>
Highlights of the performance improvements include:
- Overall Akka HTTP throughput and transfer rate has been improved by
30-40%
- Performance is on-par or better than Spray.
- Matching it both in raw throughput as well as latency distribution
across a spectrum of request rates.
- We measured an overall improvement of ~14% over Spray
- Short lived connections throughput, which remains to be the worst-case
scenario for Akka HTTP thought remains rare in the real world (due to
connection pooling), has been doubled.
- Given our EC2 infrastructure (m4.2xlarge instances) the server
currently reaches a maximum of ~160.000 “ping / pong” requests per second
(measured using 100 concurrent connections).
Happy hakking!
