Check if SSD1306Wire.h can possibly be made faster.

See here.

    bool connect() {
      Wire.begin(this->_sda, this->_scl);
      // Let's use ~700khz if ESP8266 is in 160Mhz mode
      // this will be limited to ~400khz if the ESP8266 in 80Mhz mode.
      Wire.setClock(700000);
      return true;
    }

Clock is at 700Khz, might be possible to up that on ESP32.
