This fork is compatible with the original library from `me-no-dev` regarding WebSocket, and wraps the optimizations done by `yubox-node-org` in the `AsyncWebSocketMessageBuffer` class.
So you have the choice of which API to use.
I strongly suggest to use the optimized API from `yubox-node-org` as it is much more efficient.
Here is an example for serializing a Json document in a websocket message buffer. This code is compatible with any forks, but not optimized:

Here is an example for serializing a Json document in a more optimized way, and compatible with both forks:

```
I recommend to use the official API `AsyncWebSocketMessageBuffer` to retain further compatibility.
## Stack size and queues
Here are some important flags to tweak depending on your needs:
```cpp
// Async TCP queue size
-D CONFIG_ASYNC_TCP_QUEUE_SIZE=128
// Async TCP async task core
-D CONFIG_ASYNC_TCP_RUNNING_CORE=1
// Async TCP async stac ksize
-D CONFIG_ASYNC_TCP_STACK_SIZE=8096
// WebSocket queue size
