I agree with you and present even a stronger statement: talking about GC pauses without measuring the actual end-to-end latencies may give the false impression!

I agree with you and present even a stronger statement: talking about GC pauses without measuring the actual end-to-end latencies may give the false impression! The overall throughput might look good, but threads might experience bad local latencies all over the place anyway. In Shenandoah project, that is my recurrent argument for capping the pacing stalls and going to STW mode when bounded pacing did not help.
