<DUKENUKEM> hey guys
<DUKENUKEM> at the end of the systemtap run when it gives a little summary of your probes
<DUKENUKEM> hits/cycles/variance/etc
<DUKENUKEM> what is the cycles value? how long it took for the function to finish?
<DUKENUKEM> currently i am timing function runtimes to look for a bottleneck with systemtap
<DUKENUKEM> using return probes and entry gettimeofday_ns
<DUKENUKEM> and it seems to work pretty well
<DUKENUKEM> but i was just wondering if systemtap was already showing me this information
<fche> cycles = low level rdtsc oriented numbers
<fche> but stap estimates -its own- execution times, not that of the threads / programs that its probes are inserted in
<fche> so stap -t displays more like the overhead
<DUKENUKEM> ah i see

<wcohen> DUKENUKEM, there is a measureinterval.stp script listed on https://sourceware.org/systemtap/examples/keyword-index.html#MONITORING that can be be used for collecting timing information.
<DUKENUKEM> thanks wcohen
