It looks relatively normal, please post the configuration.

How is this normal? One worker is taking up 200%, and the server has crashed.

To discuss the data volume processed (synchronized) per second by DM, how large is each record? Based on the current information provided, it’s impossible to analyze.

How should I look at this?

200% is just 2 cores… You didn’t even post your configuration…
