Webserver slow in startup and in UI

[PartTheSeas]

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.

[PartTheSeas]

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

[PartTheSeas]

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

The entire UI and start up are slow. If I F5 the Glances tab it needs like 5-20 seconds to refresh

[nicolargo]

processcount [OK] 7.35434s
sensors [OK] 2.03907s

On my side i have:

processcount [OK] 0.06198s
sensors [OK] 0.0007s

Can not explain the reason :(

I never tested Glances on Windows 11. Is another user use this OS with Glances ?

[petapika]

Niclargo, I'm also using Windows 11 Pro and have a similar issue (NPI) with initiating and getting updates from Glances to Homepage (docker widgets). Would be glad to help if I can...
