Re: Has anyone measured the time consumed by by an 8266 OTA?

For mass production you can preload the flash before putting it on the board, if that's the only thing you're worried about. There are many companies that will sell modules in bulk with the flash already loaded with whatever image you give them - this is what they do with NodeMCU units.
If you're doing smaller batches then the other thing to consider of course is that with UART flashing, you can flash maybe 12-16 units at a time max (I do 8 at a time), whereas OTA you'll be able to do over a hundred at a time if you have the power supplies for them.
But if I were mass producing then I would just get the flash pre-loaded - very simple
