Webserver slow in startup and in UI
Describe the bug I don't know how I would verify or or print this behavior, but the web server is super slow in startup (20 secs+) and if I refresh the tab in my browser it takes another 20+ secs to reload
To Reproduce Steps to reproduce the behavior: No idea if it's just me, let me know what you need and how I can retreive it
Expected behavior Startup time should be a few seconds and refreshing the UI as well at max
Environement (please complete the following information)
- Windows 11
- Glances & psutil versions: Glances version: 4.2.1 Glances API version: 4 PsUtil version: 6.1.0 Log file: C:\Users\Donatus\AppData\Local\Temp\glances-Donatus.log
- How do you install Glances (Pypi package, script, package manager, source): pip install glances[all]
- Glances test: Curses module not found. Glances cannot start in standalone mode.
An update on this.
After doing some research I found out that the windows-curses package seems not to work with python3.9 or above, so I downgraded python to 3.9 and was able to install the windows-curses package.
Glances seems much more responsive now, even though not blazingly fast, but way faster.
Could this have been the culprit? Is there anything else I can do to improve the performance on Windows?
Kind regards ❤️
Hi @PartTheSeas
On his Pypi page, Windows-curses seems to be compliant with Python 3.6 to 3.12. Did you try to install the latest version (2.4) ?
Perhaps slow start issue came from another think.
Can you also send us the result of the following command:
glances --issue
I don't know. If I install curses with python > 3.9 I get the curses error I described in my first post, so I googled a bit and downgraded to 3.9.
Can you also send us the result of the following command
glances --issue
Of course! There you go:
glances --issue

I never tested Glances on Windows 11. Is another user use this OS with Glances ?
I’m also finding about 8-20s to refresh glances on windows.
Edit: Seems like 60-120s is more common.
Edit: It appears to get worse with longer uptime. 60-120s is the worst I’ve seen still up to this point, After reset it will still take a few seconds which is far worse than macos and linux, but at least it’s kind of usable.
This issue is stale because it has been open for 3 months with no activity.

I'm having this issue as well. It seems like the main problem is that updating the process count is very slow:

I believe the perf issue with processcount is related to https://github.com/giampaolo/psutil/issues/2366 and https://github.com/giampaolo/psutil/issues/2463. Based on the description of that issue, running as admin should help, but it didn't make a substantial difference for me, and I'd like to not have to run as admin. I think this can only be fixed by psutil, though.
Same issue here.
Environment
- OS: Windows 11 WSL2
- Distro: Ubuntu 24.04 (64-bit)
- Kernel: Linux 6.6.87.2-microsoft-standard-WSL2
- Glances 4.3.3 (/app/glances/init.py)
- Python 3.12.3 (/venv/bin/python3)
- PsUtil 7.0.0 (/venv/lib/python3.12/site-packages/psutil/init.py)
- Deployment: Docker (nicolargo/glances:ubuntu-latest-full/nicolargo/glances:ubuntu-latest)
Observation
- With [sensors] enabled → startup and web refresh take 10+ seconds.
- With [sensors] disabled → everything is fast again.
- [processcount] works fine, by disabling it removes all TASKS info.
As @mlindgren said, the issue came from the PSUtil lib used under the wood by Glances to grab system stats.
Issue are the followings:
- https://github.com/giampaolo/psutil/issues/2366
- https://github.com/giampaolo/psutil/issues/2463
I let the issues opened as far as the PsUtil issues will be corrected.
