Hi everyone,

I recently upgraded my Unraid system from version 6.0 to 7.0 beta, and I've noticed an issue with unusually high CPU usage. On version 6.0, the CPU usage was consistently around 10%, but after the upgrade, it has increased to 50-60%. Additionally, the system's responsiveness has significantly slowed down—for example, it takes 20-30 seconds to refresh the Docker containers page.

Interestingly, when I stop the Docker service from the system settings, the CPU usage returns to normal, and the system operates smoothly. I’ve checked the logs but didn’t find any errors or issues recorded.

Could anyone provide guidance on how I should approach diagnosing and resolving this issue? Any help or similar experiences would be greatly appreciated!

Thanks in advance!

Hello, I have uploaded the diagnostics.

Stop the docker service and see if the usage returns to normal after a couple of minutes.

Stopping the Docker service resolves the issue.

Now re-enable the service but leave the containers disabled, if still OK, try starting them one by one, wait a couple of minutes before starting the next.

现在重新启用该服务，但保持容器处于禁用状态，如果仍然正常，请尝试逐个启动它们，等待几分钟后再开始下一个。

Even if I stop all Docker containers, the issue persists. Only stopping the Docker service restores normal operation.

Try recreating the docker folder as an image, folders sometimes have weird issues:

Also see below if you have any custom docker networks:

如果您有任何自定义 docker 网络，另请参阅以下内容：

Previously, all my containers were installed using Docker Compose, with many custom networks configured. I tried deleting the Docker image in the settings and recreating it. This time, I didn’t use Docker Compose but instead used Unraid's Docker installation method. The situation has improved slightly, but refreshing the Docker applications page still takes 10 seconds, whereas the same Docker containers on version 6.13 only take 3 seconds. Additionally, on version 7.0, the CPU usage remains around 30%, while on Unraid 6.13, it was only 10%.

Are you using an image now or still a folder?

Try to see if the slowdown happens gradually as you add containers, or if it's a specific container causing the issues.

尝试查看速度变慢是在添加容器时逐渐发生的，还是特定容器导致了问题。

Today I tried starting the containers one by one to observe the situation. When containers installed via Docker Compose are running, the Docker application page load time significantly increases to around 10 seconds. However, when I stop those Docker Compose-installed containers, the load time drops back down to about 3-4 seconds.

Can't really help with that, since Docker Compose is not stock, at least not yet.

Although the issue still persists, I really appreciate your help!
