I am running a acala node. But recently, I found it becomes super slow responding API request such as query balance? Is there a problem? I found the number of transactions in queue is extremely high ? Is there something wrong with acala node? <img width="446" height="250" alt="Image" src="https://github.com/user-attachments/assets/99b2c4a8-2e6a-4706-9a28-3f724f9e38f2" />
