Interesting! I didn't know what the max baud rate is - I imagine there will be diminishing returns pretty quickly as the rate rises past 1M baud though.
The heat'll all be coming from the ESP8266 - by comparison the STM32 doesn't draw much at all.
6k in 1.32 seconds on the low side, but I guess that's actually with multiple HTTP connections? I guess the real win will come for bigger files, so you might get a better experience by inlining your CSS.

So you can overclock the chip itself. You might just be able to run the code for 160Mhz (default is 100), but it is a different chip so I'm not sure. Apart from pointing you at the STM32 chip's datasheet on the WiFi board page there's not much I can do to help you there though - that's getting very extreme!
