# Efficient intra-process communication:
Our ROS2 Wrapper node supports zero-copy communications if loaded in the same process as a subscriber node. This can reduce copy times on image/pointcloud topics, especially with big frame resolutions and high FPS.
You will need to launch a component container and launch our node as a component together with other component nodes. Further details on "Composing multiple nodes in a single process" can be found [here](https://docs.ros.org/en/rolling/Tutorials/Composition.html).
Further details on efficient intra-process communication can be found [here](https://docs.ros.org/en/humble/Tutorials/Intra-Process-Communication.html#efficient-intra-process-communication).
## Example
### Manually loading multiple components into the same process
* Start the component:
```bash
ros2 run rclcpp_components component_container
```
* Add the wrapper:
```bash
ros2 component load /ComponentManager orbbec_camera orbbec_camera::OBCameraNodeDriver -e use_intra_process_comms:=true
```
Load other component nodes (consumers of the wrapper topics) in the same way.
### Using a launch file
```bash
ros2 launch orbbec_camera gemini_intra_process_demo_launch.py
```
### Limitations
* Node components are currently not supported on RCLPY
* Compressed images using `image_transport` will be disabled as this isn't supported with intra-process communication
