I'm not sure if it's part of upgrading to a more recent MediaWiki version, or architecture changes behind the screen, or something else, but making changes to my personal css and seeing the results has been blazing fast, no more sitting there refreshing my cache for two minutes before finally giving up and entering debug mode to see my changes. Thanks for that!

I'll ask about this. It could be that the new platform is faster overall (true), it could be that there's fewer wikis on the new codebase (also true), it could be that MW 1.33 is faster than MW 1.19 (third true), or some sort of combination of performance bonuses.

The answer is that user CSS is more performative, thanks to the special way that MediaWiki handles it, a change made after MW 1.19's release.
