I'm currently bottlenecked by cork. Probably normal.

One possible improvement I was think of is whether we could change the API so the we don't need to do a slow call back into js, i.e. instead of:

socket.cork(() => {
  sendAlotOfData(socket)
})

We could do:

socket.cork()
try {
  sendAlotOfData(socket)
} finally {
  socket.uncork()
}

Or with modern JS even:

{
  using socket.cork()
  sendAlotOfData(socket)
}
