Hmm... it was me who reviewed+uploaded the current version, and it doesn't even put a strain on my box, despite using 4× as many cores but only 64GB memory. Ie, half the memory per thread.
It also has an interesting pattern of CPU use: there's never any substantial load on any single thread, and it keeps affinity to a single NUMA node at a time: "topline -i 5" shows: nvme(⣀⠀⣀⣀⠀)sd(⠀⠀) (⡀⣀⣀⡀⡀⣀⣀⢀≬⣀⢀⣀⣀⣀⢀⣀⣀≬⢀⢀⡀⠀⢀⢀⠀⢀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⣀⠀⣀⣀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⣀⢀⡀⡀⣀⣀⠀⣀≬⢀⢀⡀⣀⣀⠀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⡀⠀⡀⡀⠀)sd(⠀⠀) (⣀⣀⣠⡀⡀⣀⡀⡆≬⣀⣀⣀⠀⣀⣀⣀⣀≬⡀⢀⠀⡀⣀⢀⢀⠀≬⡀⠀⢰⣀⡀⠀⢠⡀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣄⣀⣆≬⣠⣀⣀⣀⣀⣀⣄⣀≬⣀⣀⣀⣀⡀⡀⢀⠀≬⡀⠀⢀⣠⡀⣀⣀⢀) nvme(⣠⠀⣀⣀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⢀⠀⠀⠀⡀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⠀⢀⢀⢀⣀⡀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⢀⢀⠀)sd(⠀⠀) (⡀⡀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⡀⣀⣀⣀⣀⢀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⡀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⢀⣀⣀⣀⣀⢀⡀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⢀⣀⠀⣀⡀⠀⢀≬⠀⡀⠀⠀⢀⠀⣀⢀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⡀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⡀⡀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⡀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⡀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⣀⡀⡀⠀⠀⣀⡀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⡀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⣀⣀⢀⢀⣀⡀⡀≬⡀⠀⠀⢀⣀⠀⠀⡀≬⣀⢀⢀⢀⣀⢀⣀⢀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⡀⡀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⡀⡀⣀⣀⣀⣀≬⠀⡀⢀⣀⠀⠀⡀⡀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⡀⡀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⠀≬⢀⣀⣀⣀⣀⢀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⢀⠀⣀⠀⠀⢀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⡀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⡀⢀⠀⡀⣀⣀⣀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⣀⣀⡀⣀⡀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⡀⣀⣀⢀⡀⡀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⣀⡀⡀⣀⠀⠀⢀≬⣀⢀⣀⠀⢀⣀⡀⣀≬⣀⢀⣀⣀⣀⢀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⡀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⡀⠀⠀⠀⡀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⡀⡀⠀⠀⠀⠀≬⡀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⢀⣀⣀⣀⡀⣀⣀⣀≬⣀⣀⣀⣀⡀⣀⣀⡀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣠⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⠀⡀⠀⠀⠀⠀⠀) nvme(⡀⠀⡀⡀⠀)sd(⠀⠀) (⡀⡀⡀⡀⢀⢀⢀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⢀⢀⡀⠀⠀⢀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⢀⣀⣀⣀⣀⣀⣀⣀≬⢀⠀⡀⠀⡀⠀⣀⠀≬⢀⡀⣀⣀⣀⠀⠀⡀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⡀⡀⠀⠀⠀⡀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⡀⣀⣀⡀⡀⣀≬⣀⣀⣀⢀⣀⣀⣀⣀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⣀⣀⣀⢀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⡄⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⠀⠀⠀⠀⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⢀⣀⣀⣀⢀⢠⢀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⣰⠀⣰⣰⠀)sd(⠀⠀) (⡀⢀⠀⠀⠀⡀⣀⣀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⢀⠀⠀⠀⠀⠀⠀) nvme(⢸⠀⢸⢸⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⡀⢀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⢀⢀⠀) nvme(⢰⠀⢠⢠⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⢀⠀⠀⠀⠀⠀⠀⠀) nvme(⢸⠀⢸⢸⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⢸⠀⢸⢸⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⢀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⠀⠀⠀⠀⠀⠀⠀⠀) nvme(⢰⠀⢠⢠⠀)sd(⠀⠀) (⡀⠀⠀⠀⠀⠀⠀⠀≬⣀⣀⣀⣀⣀⣀⣀⣀≬⠀⠀⠀⠀⠀⠀⠀⠀≬⡀⠀⠀⢀⡀⠀⠀⢀) (Start and the end are sbuild setup, compilation, packing up the package, and autopkgtests, so the pattern differs.)
