A performance test where the player can test out their PC specs to know if they are good for online play, similar to Killer Instinct
I also think having an option to actually test how your connection feels in certain server areas would be great to know if your connection is stable or not or if it is playable

That is definitely needed, especially given that performance can vary wildly from character to character and from stage to stage (e.g. 4 Zetterburns on Tempest Peak VS 4 Forsburns on Merchant Port)
