I define my dictionary, which creates a pairing between a connected TcpClient and a `ClientState` instance I use to track client-specific state, such as the player's username, last heartbeat, etc.
```c#
```csharp
private readonly ConcurrentDictionary<TcpClient, ClientState> _clients = new();

When a client connects, I add them to the dictionary.

```csharp
TcpClient client = await _tcpListener.AcceptTcpClientAsync();
ClientState clientState = new(client);

Spawning thousands of threads also introduced a CPU load bottleneck in the form of 'context switching'. The CPU can only handle so many threads simultaneoulsy, roughly equal to the number of logical cores (e.g. 4 CPU cores = 4 threads, 8 with hyper threading = 16 threads, etc.) When the number of threads exceeds the number of cores avaialble, the CPU starts to 'context switch' which essentially means it flicks through all of the running threads giving them all a chance to run. This switching requires the CPU to work, which increases CPU load which would be better used processing game server requests (rather than switching between thosands of running threads!)
```c#
```csharp
TcpClient client = await _tcpListener.AcceptTcpClientAsync(); // <-- Async accpept TCP client
ClientState clientState = new(client);

A great way to optimise this approach is by using dotnet's `ArrayPool<T>`, which is a dotnet-manged pool of arrays of any given type. This way, we ask dotnet for one of its arrays every time we want to store client data in a buffer for processing, and we simply release it (i.e. give it back to the pool) when we're done. Because dotnet manages this pool--the memory is already allocated and managed by dotnet for the arrays in its pool--we don't have to reserve and release memory for every buffer, releieving pressure on both our server's memory and CPU too, as the garbage collector has nothing to clean up!
```c#
```csharp
// Get a new array for the buffer from the pool
byte[] buffer = ArrayPool<byte>.Shared.Rent(client.ReceiveBufferSize);
