Fontawesome-webfont.woff sometimes takes a long time to load

When loading the web interface after an extended period of disuse (e.g. a day or more since the last time it was loaded), my web browser (Firefox for Linux) seems to have difficulty loading /static/vendor/font-awesome-3.2.1/fonts/fontawesome-webfont.woff. It feels like the web server on my RPi 3B+ just takes a lot longer to load that particular URL.

The end result is that some plugins that use those fonts stall. In particular, OctoPrint-TPLinkSmartplug (see [BUG]: Lightbulb icon takes a long time to load 路 Issue #197 路 jneilliii/OctoPrint-TPLinkSmartplug 路 GitHub).

I understand that this probably isn't an OctoPrint bug per se. I assume the web server configuration is part of OctoPi, it could be a limitation of my RPi, or it could even be a browser configuration.

Have you checked in the devtools to get numbers on the speed of loading it rather than it 'feeling' slower? If you open the browser's devtools there is a section called 'Network' that should show you the timings for all the requests.

A test in safe mode would also be recommended to make sure a plugin is not interfering.

I'm afraid I don't see the link between this and your question?

That issue thread just has some 404 errors for woff files. I suspect that was what was being searched for in the issue tracker. Definitely seems unrelated.
