This repo contains a set of benchmarks based on the Phoronix Test Suite, that test against various different x86 microarchitectures (x86-64-v{1..4}, znver4, native, etc...)
Run ./run_all.sh to get started (with the PHP tests) and look at the results in test-results/merged.html.
After running the PHP tests, you may also run the mongodb tests with ./run_all_mongo.sh.
