No, unrelated. Basically the frankenphp builds, my php-zts repo and also the docker (bookworm) images score much lower in phpbench than remi's distribution.

Gcc --disable-gcc-global-regs: 110k ZTS
Clang build: 113k ZTS & NTS, 115k with LTO
Docker (bookworm) images: 120k NTS
Gcc from source: 136k ZTS, 137k NTS
Mostly static gcc: 137k ZTS
Remi: 156k NTS
Recompile remi's with rpmbuild (Gcc): 160k ZTS, 161k NTS

Each of these has <0.5% variance across multiple tests over the course of 2 days. Still haven't figured it out.
