> Maybe something unrelated changed on the benchmark machines? Very unlikely, it happened on two separate machines with different distributions and nothing was updated in the machines that I can see. Both use a configuration file for pyperformance that looks like this: ------------- $ cat bench.conf [config] json_dir = ~/json_cron [scm] repo_dir = ~/cpython_cron update = True remote = origin [compile] lto = True pgo = True bench_dir = ~/bench_tmpdir_cron [run_benchmark] system_tune = True upload = False [upload] url = https://speed.python.org/ environment = speed-python executable = lto-pgo project = CPython [compile_all] [compile_all_revisions] COMMIT_SHA=master
