On most systems with only four counters it'll start multiplexing, which
will give much worse results. Defaulting to non multiplexing is much
better.
Reproducing the standard perf stat output isn't that difficult. It's
perf stat -e
task-clock,cs,migrations,page-faults,cycles,instructions,branches,branch-misses
and then add more events. If you remove the bogus stalled-* events you
have even two free counters.
If you exceed four you should define appropiate groups with {}
