sydb☮x-scm improves seccomp for read only open calls which is a noticable optimization considering the overall count of trace stops, see details here: https://commits.exherbo.org/sydbox-1:8bc285f which shows remarkable improvements of reduction in open{,at} calls and build times. Apart from the commit message there’s the benchmark https://git.exherbo.org/sydbox-1.git/tree/bench/2021.05.30-paludis-seccomp-open.txt on my build host which has the timing to build the current paludis-3.0.0 (scm).
