I wonder if it is necessary to upload once every 1 second.

I wonder if it is necessary to upload once every 1 second.

If this needs to be changed, maybe it could be in a different PR as it's somewhat of a functional change? This PR only adds the configuration option so that it's visible. It is 1 second by default and therefore isn't a functional change.

Cloud u please tell me where this 1s comes from?

After reviewing the code, I found that it should actually be 3 seconds. Please correct me if I'm wrong.
