Enabling TCP_NODELAY should disable the Nagle algorithm completely,
not just shorten the send delay.

If TCP_NODELAY is enabled for stunnel is already, are you sure, your
application doesn't use Nagle?

Are you actually having a timing problem, or are you merely afraid of
one? In doubt, you might check the timing with e.g. wireshark.
