Performance Graph

Notes

• Running average load (window length is 8 sec) is calculated for all cores.(Running average* : Series of averages is calculated for a fixed window period of different subsets of the full data set and final average is calculate from the average series)
• Open source software Oprofile is used to measured the A8 thread details, Oprofile thread add some additional A8 load
