Describe the bug
Instead of <5% CPU Usage, I have around 15-25% CPU usage for glances on a Intel Core i3-8100T (running Proxmox)

To Reproduce
Steps to reproduce the behavior:

1. Install glances on Proxmox using https://raw.githubusercontent.com/nicolargo/glancesautoinstall/master/install.sh (via https://community-scripts.github.io/ProxmoxVE/scripts?id=glances)
2. Start via systemd service (/usr/local/bin/glances -w)
3. Open glances website
4. Observe high CPU

Expected behavior
Observe low CPU

Environement (please complete the following information)

• Operating System (lsb_release -a or OS name/version):
  Proxmox:

  Distributor ID: Debian
  Description:    Debian GNU/Linux 12 (bookworm)
  Release:        12
  Codename:       bookworm
  

• Glances & psutil versions:

  Glances version:        4.2.1
  Glances API version:    4
  PsUtil version:         5.9.4
  Log file:               /root/.local/share/glances/glances.log
  

• How do you install Glances (Pypi package, script, package manager, source): https://raw.githubusercontent.com/nicolargo/glancesautoinstall/master/install.sh
• Glances test:
  glances_issue.txt

Additional context
I have around 30 LXCs running in proxmox, so the processlist is quite long.
How can I further debug this?

You can also pastebin:

• the Glances configuration file (https://glances.readthedocs.io/en/latest/config.html#location): No config file
• the Glances log file (https://glances.readthedocs.io/en/latest/config.html#logging):
  glances.log

Well, I guess this is indeed part of the problem:

processcount  [OK]    0.24868s
{'pid_max': 0, 'running': 1, 'sleeping': 922, 'thread': 2347, 'total': 1091}

But I also get high CPU if I request only CPU and MEM use using the gethomepage.dev glances info widget

Strange, Glances is now optimzed for CPU consumption (on my PC, it consume ~5% CPU).

Can you try this:

glances --disable-plugin all --enable-plugin quicklook,cpu,mem,swap,load,processlist

Then it's between 8-15%, but mostly around 10%. If I remove processlist, and use top in a different shell I can see it does 3%.

Apart from opening the website, I also tried using the API by using the homepage widget, which doesn't use the processlist endpoint (see https://github.com/gethomepage/homepage/blob/a06964dd175fa798fa9189ba1ecd5766bbde543f/src/pages/api/widgets/glances.js) but still causes high cpu... is this triggered by accessing the API?
