[jolsa@krava perf]$ sudo ./perf stat -e cycles,instructions -a -x, 160517940,,cycles,2357448795,100.00,,Ghz,2357448795,100.00 ^^^^^^^^^^^^^^^^^ what's this data? 84822675,,instructions,2357537479,100.00,0.53,insn per cycle ,,,2357537479,100.00,,stalled cycles per insn,2357537479,100.00 this line is probably wrong, as noted in previous email..? thanks, jirka
