One thing thats a bit interesting with the Arduino ESP8266 support is that a lot of boards are defined in boards.txt to use DIO mode, even though the hardware itself is QIO. See the line build.flash_mode= in portable\packages\esp8266\hardware\esp8266\2.3.0\boards.txt.
For example the NodeMCU 1.0 is defined with DIO though most 1.0 modules do actually support QIO, whereas NodeMCU 0.9 is defined with QIO, so uploading with the 0.9 definition the flash will run a bit faster than when using the NodeMCU 1.0 definition.
(I've never actually come across any ESP modules that aren't QIO, does anyone know of any? Might be handy as it frees up another GPIO pin)
