### Current Behavior This is a follow-up to a [help request](https://github.com/apache/apisix/issues/11442) that was raised a few days ago and discussed with @juzhiyuan. We attempted to resolve the issue by disabling the logging of request bodies in the file-logger plugin, but this did not reduce memory usage. Surprisingly, disabling the Prometheus plugin resulted in a significant reduction in memory usage.  However, without the Prometheus plugin enabled, it becomes challenging for us to track the metrics of APISIX. Therefore, we re-enabled the plugin and encountered the initial issue again. After careful consideration of the extra labels we added, we made some changes and deployed them, which resulted in a memory reduction of 70-80%.   We also want to enable the URI label to obtain metrics based on URI. Additionally, we observed that the memory does not decrease when there is no traffic with the Prometheus plugin enabled. We encountered difficulties implementing the suggested change in the helm configurations mentioned in this link: https://github.com/apache/apisix/blob/release/3.8/conf/config-default.yaml#L175-L177. It would be greatly appreciated if you could provide a sample of how to integrate this change with helm configurations. ### Expected Behavior _No response_ ### Error Logs _No response_ ### Steps to Reproduce 1. Run APISIX with helm chart from api7 on EKS. 2. enable the prometheus plugin with extra labels as below <img width="420" alt="image" src="https://github.com/user-attachments/assets/3e7d00b8-a3d6-4e72-bb73-cccdc21c2322";> 3. Run a performance test with around 3000~4000 requests with different URIs.the ### Environment - APISIX version (run `apisix version`): - Operating system (run `uname -a`): - OpenResty / Nginx version (run `openresty -V` or `nginx -V`): - etcd version, if relevant (run `curl http://127.0.0.1:9090/v1/server_info`): - APISIX Dashboard version, if relevant: - Plugin runner version, for issues related to plugin runners: - LuaRocks version, for installation issues (run `luarocks --version`): -- This is an automated message from the Apache Git Service.
