the inference time not stable

inference time 11.890137 inference time 77.138916 inference time 14.939941 inference time 153.685059 inference time 11.651123 inference time 11.635986 inference time 18.880127 inference time 21.743896 inference time 18.770996 inference time 210.691895 inference time 15.924072 inference time 13.067871 inference time 11.803955 inference time 11.813965 inference time 12.151123 face detection time cost: min = 8.04ms max = 733.61ms avg = 64.47ms why the inference time are not stable ?

It is strange. What device did you test on? Does your CPU usage stable?

Architecture: x86_64 CPU op-mode(s): 32-bit, 64-bit Byte Order: Little Endian CPU(s): 4 On-line CPU(s) list: 0-3 Thread(s) per core: 1 Core(s) per socket: 4 座： 1 NUMA 节点： 1 厂商 ID： GenuineIntel CPU 系列： 6 型号： 158 型号名称： Intel(R) Core(TM) i5-7400 CPU @ 3.00GHz

I'm also curious,even if I don't show the result of camera, the result are not stable like below: face detection time cost: min = 8.10ms max = 272.08ms avg = 55.88ms
