Test Setup
Additional Settings
Increase the socket buffer size
It is recommended to increase the network socket receive and send buffer size to 16MB. These values can be set permanently in /etc/sysctl.d/62-buffers-performance.conf:
| Setting | Value | Description |
| net.core.wmem_max | 16777216 | Maximum memory size of a socket buffer for sending in Bytes |
| net.core.rmem_max | 16777216 | Maximum memory size of a socket buffer for receiving in Bytes |
| net.core.netdev_max_backlog | 10000 | Maximum number of packets which can be buffered if the Kernel does not manage to process them as fast as they are received |
| net.ipv4.udp_mem | 10240, 87380, 16777216 | Minimum, Default and Maximum memory size of a UDP socket buffer for receiving and sending data in bytes |
- Note
- If
/etc/sysctl.d/62-buffers-performance.confdoesn't exist beforehand, create one. - Refer to Network Performance Settings for more information.
Increase MTU
If possible, it is recommended to increase the MTU of the network card to at least 8000 bytes to enable the use of jumbo frames.
| Setting | Value |
| MTU | 8000 Byte |
Please refer to Network Performance Settings to learn about how to set this value temporarily or permanently.
Benchmarks
The following scenarios have been tested:
- When de-Bayering is carried out on the host system: The camera delivers Bayer8 image data to the host system. The Bayer8 image data then get de-Bayered to RGB8 format on the host system. This setting results in a higher frame rate but a higher CPU load as well.
- When no de-Bayering is performed: The camera delivers Bayer8 image data to the host system. No de-Bayering is performed. This settings results in a lower CPU load and a higher frame rate. The behavior is identical to monochrome cameras.
| Camera | Resolution | Pixel Format | Frame Rate [Frames/s] | Bandwidth [MB/s] | CPU Load With Image Display | CPU Load Without Image Display |
| mvBlueCOUGAR-X102nC | 1632 x 1248 | BayerRG8 (on camera) → RGB8 (on host) | 58.61 | 120.30 | ~16% | ~8% |
