I AM able to speed test and compare - see my other query - once I'm sure which code to grab I'll try it and report speed back - it is quite easy to speed up the ESPRESSIF code but this of course has additional checks for clock stretching.

As I said in post #1:
Are there somebody, that have some equipment to test the bitrate, and to try it out?
Because, I don't have.
I have it running with htu21d and wi-nunchuck or 2 htu21d with sda and scl crossed
while they only have 1 address.
