web admin: switches view is horribly slow with many roles

[ptrrkssn]

Describe the bug
The web admin switches view (Configuration - Policies -> Switches) is horribly slow / unusable if you have many role -> VLAN mappnings defined. Current we have around 90 xxxVlan=VLAN lines under "default" and them some overridden rules per switch.
Trying to open the Switches web page is horribly slow.

To Reproduce
Steps to reproduce the behavior:
Put many rules into conf/switches.conf and try to access the web UI.

Screenshots
It eventually loads, after giving a couple of warnings about slow web pages.

Expected behavior
It should be usable...

Desktop (please complete the following information):

• Linux
• Firefox
• Version 84.0
  (also tried other browsers)

PacketFence version: 10.2.0

Hi, thanks for the report, this is a known issue of the v10.x release.

There is unfortunately no easy fix for this and @satkunas is currently refactoring all the configuration section to improve the speed (especially for the switches)

This will get done for version 11.0 which will be out shortly
