CARS Stream Performance#
Test Server Configuration#
The performance of CARS Stream is measured by the number of frames processed per second. This metric depends on the parameters of the input video data:
- File resolution;
- Number of bits per color;
- Vehicle stream load.
Input data parameters used for testing CARS Stream:
- Resolution: 1920x1080;
- The approximate number of cars passing in the video file spb for the Test 1: 290;
- The approximate number of cars passing in the video file mkd_zao for the Test 2: 6.
The measured values are the average of at least 100 experiments.
The test server parameters are shown in Table 17.
Table 17. Test Server Parameters
| № | Parameter | Value |
|---|---|---|
| 1 | CPU | Model name: Intel(R) Xeon(R) Silver 4210 CPU |
| Thread(s) per core: 2 | ||
