Likely. I tried the benchmark and saw runtimes of over 5 minutes before realizing that XDebug was active and in develop mode. Adding `-d xdebug.mode=off` dropped it to 26s. That was with `opcache.jit` in the (default?) `tracing` mode. Turning it off didn't change the runtime, which is a bit puzzling. This is all with PHP8 on macOS, although I tried 8.1RC in docker and saw similar results. Something doesn't quite add up across everyone's results here, but the extremely slow result at the top of the thread is almost certainly a debugger slowing things down. Edit: I was missing `opcache.jit_buffer_size`, and saw the runtime drop to under ten seconds with that correctly configured.
