### Search before reporting - [x] I searched in the [issues](https://github.com/apache/pulsar/issues) and found nothing similar. ### Read release policy - [x] I understand that [unsupported versions](https://pulsar.apache.org/contribute/release-policy/#supported-versions) don't get bug fixes. I will attempt to reproduce the issue on a supported version of Pulsar client and Pulsar broker. ### User environment 3.0.10 jdk17 client 2.8.1 ### Issue Description When conducting consumption performance pressure tests with a relatively large number of consumers per partition (over 1000), consumption imbalance will occur: the consumption speed of some partitions drops significantly, the overall throughput declines, and message backlog eventually arises in certain partitions. ### Error messages ```text ``` ### Reproducing the issue When conducting consumption performance pressure tests with a relatively large number of consumers per partition (over 1000), consumption imbalance will occur: the consumption speed of some partitions drops significantly, the overall throughput declines, and message backlog eventually arises in certain partitions. ### Additional information _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
