MarsSeed [1] filed a deletion request for qtperf-git [2]: Unused, abandoned minimal Qt5 UI toolkit performance testing app pkg from 2016. Upstream not maintained since the same year. [a]
Qt5 is EOL since May 2023. I don't see the usefulness of keeping this package. It has 1 vote and 0 comments. [a]: https://github.com/ChristophHaag/qtperf [1] https://aur.archlinux.org/account/MarsSeed/ [2] https://aur.archlinux.org/pkgbase/qtperf-git/
