Indeed U8g2 seems to be little bit slower than Adafruit lib: See end of this page: https://www.best-microcontroller-projects.com/ssd1306.html One reason for this, is that u8g2 does a line by line output...
U8g2 fonts are bitmap fonts, they can't be scaled. However you can provide a suitable bitmap font which can be converted into u8g2 format.

Difficult to say something without seeing the code.
Maybe the 100NANO delay is too large. Can you reduce the delay caused here by reducing the 100UL factor. As long as the display still works it could be reduced.
Did you try to remove the code from U8X8_MSG_DELAY_100NANO? I still think that there is an issue with the delays.
