Where:

 percent% : is the percentage of the real time of the real time of its containing path.
            For example blah2 is 2.685% of the real time of nothing1.The sum of the percentages at the same depth
            should always be < 100% (for example depth2 1 is 0.042+5.893+11.144+20.097+21.737 = 58.913). The rest
            is unmeasured time spent.
 count    : is the number of time the measure was taken. All the measures are the cumulative elapsed time for all
            the measures. For example blah3 numbers refer to the cumulative time spent in 1000 execution of that block.
user      : User CPU time
system    : System CPU time
total     : user+system
