Fluss version

main

Minimal reproduce step

When in low traffic, the sender finds no records ready to send, sleeps 1ms, and then runOnce again to check whether records are ready which causes a busy loop to occupy more CPU..

What doesn't meet your expectations?

N/A

Anything else?

If I modify it to sleep 50ms, the CPU will be reduced from 120 to 80... But we will need a more sophisticated mechanism to solve it..

Are you willing to submit a PR?
