Ahh, it could well be an ESP32 SPI issue in your case - the folks working on it are doing a great job (especially as they're just doing it for fun), but I think the focus is still on getting things supported and bug-free, and not on outright speed.

The esp32 esp-idf provides a function to write x bytes, but the espruino code calls it in a loop a single byte at a time, so this would have to be rewritten to support mutli byte sends.
Espruino is a JavaScript interpreter for low-power Microcontrollers. This site is both a support community for Espruino and a place to share what you are working on.
