Important note for MacBook Pro

Before testing, system activity is monitored to preclude background activity interfering with tests. For example, Spotlight indexing, a wayward daemon process offering no useful control over the timing of its indexing. But it generally settles down to doing nothing a minute or two after reboot.

Highly variable results were seen with the 2021 MacBook Pro M1 Max. For example, 133 or 153 or 169 seconds for Fujifilm GFX100S raw conversion. Ambient temperature range 80°F to 90°F.

Further testing suggests that in the 80°F range or hotter, running one test can heat up the laptop, slowing subsequent ones. It also means that long-running tests might never run at full speed if the ambient temperature is too high. Which makes the MacBook Pro a poor choice for sustained workloads in warm environments. The 2022 MacBook Pro M2 Max is likely to suffer from similar behavior, but it was tested at a far lower ambient temperature of around 65°F back in early spring, so no insight available on that. Bottom line: for reliable performance in warmer temperatures or with long-running workloads, steer clear of laptops.

No performance variation was seen with the 2023 Mac Pro vs temperature (its cooling system is world class!), but as of July 2023, it has its own Slow Mode bug related to sleep/wake.
