Comment 38 for bug 1372413

Pat, I use something such like the following awk script to parse the data:

{
        if ((NF == 5) && ($4 != "PID")) {
                total[$4] += $1
                usr[$4] += $2
                sys[$4] += $3
                cmd[$4] = $5
        }
        if ((NF == 5) && ($4 == "PID"))
                n++
}
END {
        for (i in total)
                printf "%10.2f %10.2f %10.2f %s\n", total[i], usr[i], sys[i], cmd[i]
}

awk -f cpustat.awk < cpustat.log | sort -nr | head -20

So it does seem that upowerd is consuming the most cycles. Attached is a spreadsheet and a graph from the raw stats
