Usage: perf report [<options>] -b, --branch-stack use branch records for per branch histogram filling -c, --comms <comm[,comm...]> only consider symbols in these comms -C, --cpu <cpu> list of cpus to profile -d, --dsos <dso[,dso...]> only consider symbols in these dsos -...
perf可以统计或采样的event有很多,如果我们要分析cpu,那么我们可以使用cpu-cycles、cpu-clock来衡量占用cpu的程序的分布情况,还可以通过cache-misses、page-faults、branch-misses等event来分析造成cpu占用高的底层原因,确定原因后方便优化。 如果我们要分析内存、io、网络等,也可以通过其他event来进行分析,perf可以使用的e...

Linux Load Average is a measure that tells us how busy the CPU (the main processor of the computer) is with current tasks and those lined up to be processed. Note that this is different from CPU Usage, which gives us a snapshot of how much the CPU is being used at a particular mome...
Because large portions of physicalmemoryare typically shared among multiple applications, the standard measure ofmemoryusage knownasresidentsetsize (RSS) will significantly overestimatememoryusage. PSS instead measures each application's"fair share"of each shared area to give a realistic measure. ...
