Good questions. I've been having similar problems for a while, for me, the UI in general is frozen, including the navigation buttons and query text boxes. Delay depends on the size of the json - if I do a request for 1000 rows with just 1 field each, it's a permanent 5s delay on scrolling and the text boxes and navigation buttons start working after a bit. If it's larger - e.g. 10000 rows with 1 field each, or 10 rows with lots of large fields - then it just freezes indefinitely as far as I can tell. Smaller queries - e.g. 100 rows with 1 field each work fine.

I don't see any errors in the console. The problems start around the time it starts chunking the json response, which may just be coincidence, but I think there are a few differences in how Chrome processes chunked responses. Although the response has a content-type of application/json set, which should avoid those problems.

Firefox handles all of these queries without any problem.

A query for *:* is not necessarily a simple query, it depends on how many and 
large fields you have etc. Try a query with fl=id or fl=title and see if that 
helps.

I still see this issue with Chrome and the admin console. I am using Solr 7.3

In the Chrome console I see an error:  "style.css:1 Failed to load resource: the 
server responded with a status of 404 (Not Found)"

This used to work.

It is unusably slow, even with a simple query like *:*

I have seen slowness when the result is a very large json but not for ordinary 
queries. How long delay do you see? Is it only for query panel or for the UI in 
general?

Check for popup and other tracker blockers. It is possible one of the
resources has a similar name and triggers blocking. There was a thread
in early October with a similar discussion, but apart from the
blockers idea nothing else was discovered at the time.

An easy way would be to create a new Chrome profile without any
add-ons and try accessing Solr that way. This would differentiate
"Chrome vs Firefox" and "Chrome vs Chrome plugins".

Hi - could you provide more details, such as Solr and browser network
logs when using Chrome / other browsers?

Did a recent change to Chrome cause this?

In Solr 8x, I'm not seeing slowness with Chrome on Mac.

I'm using chrome Version 78.0.3904.108 (Official Build) (64-bit)

The work around is to use Firefox
