cmd/kepler/main.go

 // Returns empty slice if GPU is not enabled or no GPUs are available (soft-fail).
 func createGPUMeters(logger *slog.Logger, cfg *config.Config) []gpu.GPUPowerMeter {
 	if !cfg.IsFeatureEnabled(config.ExperimentalGPUFeature) {
-		logger.Info("GPU feature disabled")


i don't agree that this is noise.

This creates confusion. If something is not used why logging then?

This commit removes the GPU related log noise that appears when the experimental GPU feature is disabled Signed-off-by: vprashar2929 <vibhu.sharma2929@gmail.com>

⚠️ Variability in pprof CPU and Memory profiles
When comparing pprof profiles of Kepler versions, expect variability in CPU and memory. Focus only on significant, consistent differences.
