Overview
Comment:extended performance test-suite, since max-count is implemented in timerate, usage `::tclTestPerf::_test_run ?-no-result? reptime lst ?outcmd?`; update timer-event.perf.tcl for better readability (covering execution in multiple iterations now regarding max-count, so provides more precise result now); removed unused test-cases here (new cases of event-perf-branch only).
