System factor need to be considered or be noticed

[AnterCreeper]

1. OS
   I don't know how Windows behaves.
   In Linux, schedutil gives 5ns~10ns more than performance

2. x86 perf bias msr
   It greatly affected the result as it may affect the clock of bus.
   at performance it gave 40ns~.
   at power it gave 100ns+

3. nice value
   In my test, it doesn't affect too much

4. core loads.
   If the bus is busy(for example using graphic cards, heavy programs) the latency will higher.

some factors should the user control, others like OS can be displayed in the chart.
