I have run it locally but it takes a lot of time.
nbody python3-3.7.5-1.fc30.x86_64: Mean +- std dev: 217 ms +- 2 ms nbody -fno-semantic-interposition: Mean +- std dev: 203 ms +- 3 ms - 6.9% nbody static linkage claim: -27% So -fno-semantic-interposition does help but it is not the whole static gain.
