Hi, just come when debugging some slowdown in yast[1] that ruby 2.7 ( one in TW ) removes profiler. What is result? Y2PROFILER=1 no longer works. Do you know about any lightweigth alternative? Advantage of builtin profiler was that was part of ruby, so no additional dependencies are needed. Josef [1] https://bugzilla.suse.com/show_bug.cgi?id=1189617#c6
