Scala vs Erlang Actors

Thanks to Paul Keeble for getting this benchmark project started a few years back.

Benchmark for testing Actor implementations on Scala and Erlang.

The Actor has 2 responsibilities:

• Add a count X to the Actors current tally
• Output the current count and reset the agent count to zero

Usability of these benchmarks

We know that these benchmarks are not representative for 99% of actor use cases, the simple idea is to get number of msgs/sec put thru the actor without having it do too much.

Erlang OTP

Compile the 3 files then run client:runTest(3000000).

Erlang bare receive version

Compile server2 as well as the 3 files for OTP and then run client:runTest2(3000000).

Scala

Actors being used are Lift Actor, Akka and our own Wactor.

Simply run ./sbt run and select one of the benchmarks.

2011 results on Scala 2.9.1 vs Erlang 5.8.5

I wrote Scala, Akka and Erlang Actor Benchmarks when i was really starting out with Scala.
