Akka.Coordination 1.4.27

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. Performance Fixes** In [RemoteActorRefProvider address paring, caching and resolving improvements](https://github.com/akkadotnet/akka.net/pull/5273) Akka.NET contributor @Zetanova introduced some major changes that make the entire `ActorPath` class much more reusable and more parse-efficient. 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 ``` 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.
