If a 0.4mm nozzle is 4x the area of a 0.2mm nozzle, should I print 4x faster with a 0.2mm nozzle?

Context - I think I’m having heat creep and printing too slow. (ender 3, pla 210c)

    You say you think you’re having heatcreep issues, what exactly are the issues you’re having?

    there’s a swelling of the filament, about 1" tall, above the hot end.

    Related - I’ve replaced the PTFE tube with a higher quality one and I’ve replaced the nozzle (it was indeed clogged).

      Did you follow some guide when replacing the nozzle and bowden tube? Did you hot tighten it when putting them back?

      What speed are you printing at, which you think is too slow? What’s your acceleration?

        No, it’s pretty intuitive so I just did it.

        Did you hot tighten it when putting them back?

        Yep.

        What speed are you printing at, which you think is too slow? What’s your acceleration?

        I was printing a speed test, the inbuilt one from Orca Slicer. Starts with a huge, slow brim, then low speed 10 layers, then slightly faster 10 layers, repeat until it fails.
