WebSocket performance / benchmarking

[KhafraDev]

I haven't seen any benchmarks for undici's / node's WebSocket yet and not much has been done to improve performance.

[tsctx]

What do you think of this? https://github.com/tsctx/ws-masking/blob/main/initialize.js
It uses int32 and processes 4 chunks at a time, making it 8 times faster than the current implementation.
