Release Date: 2021-09-29 // over 2 years ago-
๐ Maintenance Release for Akka.NET 1.4 Akka.NET v1.4.27 is a small release that contains some major performance improvements for Akka.Remote.
๐ Performance Fixes ๐ In RemoteActorRefProvider address paring, caching and resolving improvements Akka.NET contributor @Zetanova introduced some major changes that make the entire
ActorPath
class much more reusable and more parse-efficient.๐ Our last major round of Akka.NET performance improvements in Akka.NET v1.4.25 produced the following:
OSVersion: Microsoft Windows NT 6.2.9200.0 ProcessorCount: 16 ClockSpeed: 0 MHZ Actor Count: 32 Messages sent/received per client: 200000 (2e5) Is Server GC: True Thread count: 111 Num clients, Total [msg], Msgs/sec, Total [ms] 1, 200000, 130634, 1531.54 5, 1000000, 246975, 4049.20 10, 2000000, 244499, 8180.16 15, 3000000, 244978, 12246.39 20, 4000000, 245159, 16316.37 25, 5000000, 243333, 20548.09 30, 6000000, 241644, 24830.55
In Akka.NET v1.4.27 those numbers now look like:
OSVersion: Microsoft Windows NT 6.2.9200. ProcessorCount: 16 ClockSpeed: 0 MHZ Actor Count: 32 Messages sent/received per client: 200000 (2e5) Is Server GC: True Thread count: 111 Num clients, Total [msg], Msgs/sec, Total [ms] 1, 200000, 105043, 1904.29 5, 1000000, 255494, 3914.73 10, 2000000, 291843, 6853.30 15, 3000000, 291291, 10299.75 20, 4000000, 286513, 13961.68 25, 5000000, 292569, 17090.64 30, 6000000, 281492, 21315.35
๐ To put these numbers in comparison, here's what Akka.NET's performance looked like as of v1.4.0:
Num clients (actors) Total [msg] Msgs/sec Total [ms] 1 200000 69736 2868.60 5 1000000 141243 7080.98 10 2000000 136771 14623.27 15 3000000 38190 78556.49 20 4000000 32401 123454.60 25 5000000 33341 149967.08 30 6000000 126093 47584.92
We've made Akka.Remote consistently faster, more predictable, and reduced total memory consumption significantly in the process.
