      Description

      During code review for JDK-8232634, it was noted [1] ICMColorDataTest¹ completes 300_000 iterations on macOS in about 3 minutes whereas on 64-bit Windows it usually takes more than 30 minutes.

      It makes sense to investigate where the most time is spent on Windows. [2][3]
