* Improved sampling performance * Sampling tweaks - backtrace::get() returns vector of string_view - further performance improvements - tweaked _use_label - wrapped samples in perfetto "samples [omnitrace]" block - samples in TID=0 in sampling mode are in separate thread row * Fix empty HW counter desc + category for sampling - fallback to to metric name if papi event info description not found - add perfetto sampling category * Limit the SIGALRM frequency
