I have compared 2 Filments in speed of print.
A: Bambu Lab PLA Basic
B: Other vendor
Both settings complete identical, but hugh difference in printing time.
Ecspecially inner and out walls differ mor than factor 2!
Did I miss anything?

Why did you blur the name of the “other” vendor?
I don’t want to blame other vendors. It was a principle question.
My guess would be that they simply take the profiles provided, or slow them down to insure the filament prints with good results. If they gave faster speeds, then filament then didn’t print correctly, then they get blamed for that too. The safer option would be to make sure it prints instead of a failure. Given that a user can increase parameters at any time it’s not really an issue.
You can simply do a test to see what speed/flow the filament would support and go from there.

Bambu’s Generic PLA profile has a MVS of only 12mm³/s, which could have accounted for the speed difference, but that is not what is shown.
The Bambu profile and the “other” are have equal max volumetric speeds of 21 mm³, so I’m now wondering where that “other” profile came from, and was there an “other” process profile as well.
Same project, same process profile.
Top is calibrated Overture Black PLA, based originally on Generic PLA. Bottom is Bambu PLA Basic.
Both have MVS of 21 mmÂł/s.
Times are essentially equal.
OK, i found the difference. It’s the layer cooling threshold which is 4s for Bambu PLA and 8s for generic.
