toplev: Run perf tests only once for large systems #374

Open ak-intel opened 3 years ago

ak-intel commented 3 years ago

On systems with many CPUs perf starts rather slowly. toplev and ocperf together run perf 5 times. Should combine all these tests into one to improve startup time.

With ef583f7c45cd1 the number of perf calls is reduced by 2.
