Avoid copying buffers before passing to SSL_write if there are zero length buffers involved. Only copy the data when the buffer has a non zero length. Send a memory allocation hint to the crypto BIO about how much memory will likely be needed to be allocated by the next call to SSL_write. This makes a single allocation rather than the BIO allocating a buffer for each 16k TLS segment written. This solves a problem with large buffers written over TLS triggering V8's GC.
