This is going to sound mean however I say it, so I'm not going to sugar-coat it: that's how pretty much all suckless software works. Software becomes fast via profiling and optimization, not by ritualistically applying dubious notions of simplicity (C is simple? since when? UNIX is simple? since when?).

As pointed out above, suckless isn't focussing on macOS/XQuartz users. The latency of "linux-st" isn't that bad according to the plots of the author.

In my view, simplicity often leads to better performance as a side effect -- but of course there are many exceptions.

Nevertheless, I wouldn't start optimising software unless the software is really unusable. Optimising software to look well in rare corner cases is not a good idea imho, if the price is adding a lot of complexity.

To be fair, suckless never claimed to care about performance.

"Slow and featureless" isd hardly an advertisement for good software.

"Minimalist", "easy to understand" might be.
