codelipenghui opened a new pull request, #20607: URL: https://github.com/apache/pulsar/pull/20607
### Motivation The issue should only happen on the topic with many producers, and the max producer limitation is enabled. When a new producer is added, the broker will check all the existing producers and filter out the remote producer (from the replicator), which will run out of the CPU resource for a short period of time. <img width="1907" alt="image" src="https://github.com/apache/pulsar/assets/12592133/14e74ed2-7ace-429b-9352-c643995e0e27";> [profiler.html.txt](https://github.com/apache/pulsar/files/11788992/profiler.html.txt) ### Modifications A counter will be much more efficient instead of going through all the producers. So a new userCreatedProducerCount is added to the topic. ### Verifying this change The existing tests already covered the max producer limitation. The change will not affect the correctness. ### Does this pull request potentially affect one of the following parts: <!-- DO NOT REMOVE THIS SECTION.
