Comment 5 for bug 1882279

@Dustin,

I used a Docker image that comes with php precompiled (php:7.4-cli, see my Dockerfile above) but still managed to reproduce the performance difference, so I don't think it's building from source on the same machine that will run the php perf test that makes the difference. The difference likely comes from a compile-time flag or optimization. I'm convinced that compiling php from the Ubuntu source package would produce the same "slow" php.
