      Description

      We're calling several GPU stuff initialization methods over and over again (amounting to 1% of CPU time), this should rather be cached, see:

      • AST2BOpContext.initGPUEvaluation
      • DefaultOptimizerList.initGPUFastRangeCountOptimizer
      • DefaultOptimizerList.initGPUAccelerationOptimizer

      See attached screenshot.
