I am getting the below warning message when I subscribe to '/zed2i/zed_node/obj_det/objects' via python node

[WARN] !!!!! DEPTH/RGB ASYNC !!!!! - Delta: 1490.29 sec

and this delta keeps on increasing. Is there a fix for this or am I doing something wrong while subscribing to it?
Ubuntu 20 Desktop
ROS2 Foxy
ZedSDK 3.7.2
HD720 resolution
15 grab_frame_rate

What kind of device are you using? Is it a desktop PC, a laptop or a Nvidia Jetson board?
What ZED ROS Wrapper modules are you using?
Resolution? Framerate?

It’s not possible to debug a behavior if important details are not provided.

I had updated my question with the information you asked for

What is the GPU card that you are using?
The async/latency issue that your are facing is usually due to a not powerful enough hardware.

Your system is overloaded, please use Ubuntu tools to understand what is taking so many resources.
I suppose that your Python node is blocking the system in some way.
