Is the QPS balanced? You can check the QPS by instance in the TiDB monitoring.

Which instance did you connect to for batch insertion? Did you connect to both and insert separately?

| username: TiDBer_Terry261 | Original post link

I am using the tidb-loadbalance driver, and each TIDB node receives requests.

Is the QPS uneven?

That is the imbalance of balance.
