This mechanic perplexes me.

Rush order wording it as significantly faster confuses me.

Using it seems like it's almost as fast as my current normal cooking speed (+23) but it feels...not really different, not even faster?

What is it? x2? sure doesen't feel like it if it is. Has anyone figured out the speed change?

@Pizza I just placed a regular order of catfish and timed each individual cooking and then a rush order. Catfish are normally supposed to last 1 minute. However, due to my level it lasted about 44 seconds (which checks out, I am lv55 meaning I get a 27.5% speedbonus).

Then after I put in a rush it only took about 25 seconds to cook a catfish. It's hard to say for sure cause my internet is spotty, but that seems to be about a 45% speedboost after my level speedboost or an additional 30% on top of my level speed boost (because I only calculated it at lv55 it is impossible for me to say how it is calculated exactly.)

@Gaia

Interesting! merely ~30% speed bonus seems just in line with being barely noticeable.
I should check out how your results compare with my catfish at level 47
