well, I would say from my perspective, it might be not, because multi-threading process would spread the process on multi thread your CPU has, imagine doing heavy 3D rendering task with only single core instead multi core, but I can only do hope it wouldn't hit performance much (if 1000hz multi-threading really hit performance) compared to recent version of LFS today (7E), since LFS so far the most efficient program (or game) that could even run on very potato PCs
sorry if OOT, I'm just replying this one
