Master Stack Benchmark

Size of Process Data: 30 byte (18 byte Inputs / 12 byte Outputs)

Cycle Times in μs
Required	50	100	50	100	50	100	1000
Average	49	109	49	99	50	99	~980
Jitter	-1	9	-1	-1	0	-1	~-20
Minimum	43	104	39	86	42	89	~400
Maximum	57	123	59	113	57	111	~10000

* - "50μs" is set as kernel clock time
** - "100μs" is set as kernel clock time (as "cheater" operation by decreasing of OS's timer period)

Size of Process Data: 1630 byte (1586 byte Inputs / 44 byte Outputs).
