Esp8266 upload speed

Just migrating from Arduino to pio for my esp8266 projects. Currently I’m working with a Wemos/Lolin D1 mini. When uploading with pio the transfer takes at least twice as long as under Arduino. How can I fix the upload speed ?

upload_speed = 921600

(or the max speed your USB-UART converter can handle) in platformio.ini .


Thanks, yes this works perfectly !
