[BUG] Performance Issue: Slow Page Load Times (500-700ms) on ARM64 Devices

[codenamek83]

Is there an existing issue for this?

• I have searched the existing issues

Current Behavior

I have consistently experienced slow page load times ranging from 500 to 700 ms on a Raspberry Pi 4 with 8 GB of RAM. This sluggishness is particularly noticeable when navigating between pages on BookStack instances deployed as Docker containers on these devices. After troubleshooting the issue with Dan Brown, the developer of BookStack, it was confirmed that the problem is caused by the absence of the PHP opcache extension. The troubleshooting process and results are documented in this GitHub issue in the BookStack repository.

Expected Behavior

The acceptable page load time should be somewhere between 100–200 ms.

Steps To Reproduce

You should be able to reproduce this issue on any Raspberry Pi device, and I assume this would also be the case for any ARM-based SBC without a native SATA connection between the hard drive and the device.

Environment

- OS:Debian GNU/Linux 11 (bullseye) aarch64
- How docker service was installed: Manual install.
