(QUESTION) Avoidance of anonymous function creation on each Connection.write invocation

https://github.com/sidorares/node-mysql2/blob/4c1a807a5025c7fe332d0b621547e2788b876375/lib/connection.js#L248

We create a new anonymous function for each write operation on Connection (which can be called up to 2 times, when we send header and body for large packets separately), while all it's doing is passing stream error to connection._handleNetworkError.

Could we benefit from lazily binding _handleNetworkError to connection instance (AFAIK, .bind() got significantly faster, at least in recent versions of Node) and alway passing the same bound function on .write() invocations?

I am just guessing here, so may be any benefits are negligible. But if it worth at least researching, I would gladly do it, if it wasn't done earlier.

Start by reading lib/connection.js around line 248 and trace how Connection.write passes stream errors to _handleNetworkError. Compare the current callback allocation with lazy binding, then benchmark writes including large packets split into header and body. Done means preserving error behavior while showing a meaningful performance benefit or documenting that the benefit is negligible.
