You evidently already know the answer... only do lws_write() from the WRITEABLE callback.
Instead of doing your write when you feel like it, regardless of the state of the remote peer, change your code to instead ask for a callback when (the remote peer is) writable only. Do the actual write in the callback.
Then your writes will take place at the slower of when your code wants to do them and the rate the individual peer can accept them, which reflects the best that can be achieved.
