1. "perf top" - didn't know about this. interesting.
2. 'top' shows more then 'perf top' - it shows memory consumption, it shows time spent waiting for I/O (which won't show on 'perf top'), it shows the spread of processes and threads across the CPU cores.
i say - why not use both? --guy On 11/11/2013 07:25 AM, Elazar Leibovich wrote:
While the point of perf not being available to non-root out of the box are valid (though, it's just apt-get install linux-tools + echo 0|sudo tee /proc/sys/kernel/perf_event_paranoid away, and it's the best bargain you'll ever make), IMHO this is indeed apple vs apple comparison. The goal of top's user is identical to the goal of perf's user - to find bottleneck in a live system.
