      Description

        There is a variability of ~13% on x64 and 49% on ARM week to week with Renaissance-Scrabble. This variability is also seen in sequential CI pipeline builds, then it will flip again in a few builds.

        Running with -Xshare:off makes the high scores and the low scores more or less meet in the middle.

        I haven't yet found the earliest time where this started to happen.
