After a little more research I discovered that Tomcat 9.0.82 fixes the issue with static files not being served properly. Here is the relevant section of the release notes:
- Correct a regression in 9.0.81 that broke HTTP compression. After switching out the tomcat jar files in 6.6.13 to use version 9.0.82 instead of 9.0.81, all static files are properly served again. I'm actually not sure why CAS isn't already using this release since *tomcatVersion=9.0.82* is set in gradle.properties for 6.6.13. Still no progress on why CAS has become so much more sluggish though so any thoughts continue to be appreciated on troubleshooting that. Thanks!

When running 6.6.13, a number of .js files would not load due to a *net::ERR_HTTP2_PROTOCOL_ERROR* error. After downgrading to 6.6.10, there were no errors. I also attempted 6.6.11 and 6.6.12 and while there are no errors, it is also extremely slow to respond. At least on the first page load for any of the configured service registries and the processing of their logins. After that it speeds up but is overall slow compared to 6.6.10. I noticed that the version of Tomcat increases with each release so I did a test of switching the tomcat-*.jar files in 6.6.10 with those distributed with 6.6.13; this switches from running Tomcat 9.0.78 to 9.0.81. After doing so when I access the CAS login page, I again am unable to load a number of .js files due to the same error. I then did a similar switch with 6.6.13 to downgrade Tomcat to 9.0.78. After doing so there was no problem loading the .js files. There was a slight quirk with what I believe is a custom label in my theme. Now, this only seems to maybe address the issue of the .js files not loading. There also appears to be a much slower initial response to page loads and a slightly slower continual response to page loads and login responses. I would appreciate any thoughts on how to continue to troubleshooting what is happening. Oh, one final note. I did try out the latest 7.0.0 snapshot and found that the .js not loading is not a problem there but the slow response is. Thanks!

But all subsequent calls are fine as long as the browser is not restarted. This has been experienced with Firefox, Chromium and Edge on both Linux and Windows. Of course, everyting was fine with the current 6.4.2. I order to investigate in a neutral context, I gave a try to the stock "apereo/cas:6.6.13" official Docker image and the problem also occurs. As it is very easy to try different versions with Docker images, I did the same with "6.6.12" version : no problem at all, everything is fine from the beginning. I also wanted to build it with my own configuration and additions, but I am a bit lost with releases, as "6.6.12" and "6.6.13" archives contain "7.0.0-SNAPSHOT" stuff. The one tagged as "cas-overlay-template-20231031143146" is also "faulty" and as was not able to get any "6.6.12" archive or earlier. Fortunately, I had downloaded a "6.6.10" release which is working correctly. In case of severe "updatemania", I can still deploy this one. Using the web development tools to debug page rendering shows there is a huge amount of spent with JS inclusions with the "faulty" versions. So I think there is something wrong with those JS librairies, as disabling JS in the browser allows the page to be rendered in a snap. But of course, it's not a viable option IRL unfortunately :-( I can sound vain, but with more than one thousand users almost threatened with death if they don't switch off their computer every night, I don't want to expose ourselves to a support tickets storm saying "something is wrong with x or y application", just because morning login phase has become excessively slow :-) Is there a workaround ? JS is definitely not my cup of tea so I have no idea how to fix that or what to replace.
