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.
