High CPU usage - File editor

Configuration
1

Hello,

My home-assistant instance is running slow. It is a thin PC running HAOS.

When I check CPU usage, I see it is around 20 and sometimes 40%. only about 55% of memory is used. So I would expect it to be able to be reasonably responsive.

At times, I saw file editor (File editor, Current version: 6.1.0), that runs in its own container, using 10-15% CPU. I believe I only have one browser window on it and so cannot even imagine what it could be doing.

Any ideas of what I should look into?

Some info on my instance:

  • Installation method Home Assistant OS

Core 2026.9.1

Supervisor 2026.09.0

Operating System 18.2

Frontend 20260826.6

Versions of HA this year have begun having more and more trouble with 1GB of memory, and the likely minimum now is more like 2gb. |
How much memory are you running?

I have 8Gb RAM DDR3 1600MHz PC3L 12800 SODIMM 204 Pin . I upgraded to this a year ago.
