LMS web interface update time lag

Hi everyone,

I am new to Squeezebox and am happy to have set up my first LMS with
local Squeezelite on a RPi - with lots of help from your forum.

Intended application:
- run internet radio stations
- user interface (with reduced user interaction)
-- control playlist of preferred stations via Apple remote A1156
(play/pause, volume up/down, next/previous station)

Setup:
- RPi 3b+
$ cat /etc/debian_version
10.10
$ cat /etc/os-release
PRETTY_NAME="Raspbian GNU/Linux 10 (buster)"
- LMS via mysqueezebox.com/download
Version: 8.1.1
Platform: Debian/Ubuntu Linux ARM
File: logitechmediaserver_8.1.1_arm.deb
- Squeezelite on same RPi via 
$ sudo apt install squeezelite
squeezelite is already the newest version (1.8-4.1+b1).
- LMS and Squeezelite startup on boot
- lirc to receive A1156 data and python script to send commands to LMS
via telnet

Issue:
- while LMS responds immediately (ca. within about 500ms), the web
interface (e.g. status_header.html or material) is updated only after
2-3 seconds which is especially annoying when browsing

Minimum working example:

Code:
--------------------
    
  $ telnet localhost 9090
  Trying ::1...
  Trying 127.0.0.1...
  Connected to localhost.
  Escape character is '^]'.
  playlist index -1
  00%3A00%3A00%3A00%3A00%3A00 playlist index -1   
  stop
  00%3A00%3A00%3A00%3A00%3A00 stop
  play
  00%3A00%3A00%3A00%3A00%3A00 play
  pause
  00%3A00%3A00%3A00%3A00%3A00 pause 
  play
  00%3A00%3A00%3A00%3A00%3A00 play
  mixer volume 0                
  00%3A00%3A00%3A00%3A00%3A00 mixer volume 0
  mixer volume +30
  00%3A00%3A00%3A00%3A00%3A00 mixer volume %2B30
  
--------------------


How can I make the web interface to update immediately to allow for
interactive browsing?

Thx in advance.

Keep save, Jens
