Switch version portable mode have optimization issue?

Title: Switch version portable mode have optimization issue?

Summary: I have a lot of suturing when playing the game in portable mode, sometime, match pause for like 5 seconds in online mode, i think i also have framerate issue?
This issue happen sometime but less often in docked mode.

Notes: Please note that it might be due that i play on wifi , i’v heard the Rollback isn’t that good on wifi, but on PC (connected in Ethernet) game run perfectly, like i could have played against a player from across the world fine.
