Why my stylo benchmark times jumped 2x — anyone seen this?

Hey all — I updated my build last week and my wall-clock benchmarks now show a 2x regression. Nothing else changed on the box. Anyone hit this?

Did you rebuild in release mode? Debug builds silently skip LLVM optimization passes and the wall-clock numbers you get are not representative of anything shipped.

Also check if your OS updated clock source. I've seen TSC drift after kernel updates on older AMD hardware, which throws off every wall-clock measurement.

Both good suggestions. Turned out to be CPU frequency scaling — governor flipped to powersave after a reboot. Setting performance governor restored the 1x numbers. Thanks everyone.
