High idle CPU usage (~17%) on Docker Swarm (ARM64) #253

Description

I've been running TaskTrove on my self-hosted server and noticed unexpectedly high CPU usage even when idle (no active users or interactions).

Environment

TaskTrove Version: latest (Docker image)
Deployment: Docker Swarm
Host OS: Ubuntu 24.04 LTS (aarch64) |
Architecture: ARM64 (Oracle Cloud Ampere A1)
CPU: 4 OCPU
RAM: 24GB
Container Memory Limit: 512MB

Observed Behavior

When monitoring with docker stats, TaskTrove consistently uses ~17% CPU even when:

• No browser tabs are open
• No active users
• No background tasks running

CONTAINER    CPU %     MEM USAGE / LIMIT
[TaskTrove]      17.56%    178.4MiB / 512MiB

Expected Behavior

Idle CPU usage should be minimal (< 5%) when there are no active connections or tasks being processed.

Additional Context

I've seen similar reports about Next.js 15+ having higher idle CPU usage compared to earlier versions:

• next-server (v15.2.2) process idles high with high cpu vercel/next.js#77192 (next-server idles at 15-20% CPU in v15.2.2)

Since TaskTrove uses Next.js 16, this might be related to the framework's behavior rather than TaskTrove-specific code.

Questions

1. Is this expected behavior for the current architecture?
2. Are there any configuration options to reduce idle CPU usage?
3. Would switching to standalone output mode help?

Love the App! ❤️

Despite this issue, I really enjoy using TaskTrove! The UI is beautiful and intuitive. Just hoping to optimize resource usage on my self-hosted setup.

Thanks for the great work!
