Performance for NCS sticks not what I expected NCS 2 slower?
I have been using the NCS 1 compute stick for some time now.
I installed OpenVino version 2018 4.420 on my older i5 Ivy Bride 1.7ghz 6GB DDR3
The Demo Security Barrier Camera with no NCS sticks ran at 29ms ~ 34fps
The vehicle detection time was 11.8 ms
So I was looking forward to even better performance and much to my shock
with one NCS2 and one NCS1 I got ~10 fps.
Unbelievable, the CPU only version ran 300% faster.
Total time was 95.57ms ~ 10fps
The total vehicle detection time was 81.86 ms
With just the NCS 1 plugged in the performance was a bit worse 107.28ms ~ 9fps
Vehicle detection time was better 78.9ms ~ 12fps
With just the NCS 2 plugged in the performance was a bit worse 107.8ms ~ 9fps
Vehicle detection time was better 86.29ms ~ 11.7fps
Proving newer is not always better? I am totally perplexed by the results. I expected the NCS 2 to outperform the NCS 1 because of the additional shave cores intead the NCS 2 performed worse.
Intel any explanations? And why is my OLD i5 cpu performing 800% better with vehicle detection.
Is there something wrong with the demo code and MYRIAD?
