Slowness on Domain, Domain Info and Domain Requests

[abroddrick]

Current Behavior

Domain Requests, Domain and Domain info tables on django admin are slow to navigate to and to apply filters on with large amounts data. In general they are slower than they were before even on smaller data sets (though small data sets make the difference harder to see in some cases).

Expected Behavior

It shouldn't take more than 2 seconds to load a page, really less than a second is what a user is expecting for going to a page or applying a filter. This ticket should bring down the load time as much as possible, ideally to < 1 second, but 2 seconds would also be acceptable in the meantime.

Steps to Reproduce

1.go to django admin
2. got to Domains
3. see the long load time

*Note occasionally it seems to load at a reasonable speed, in which case clicking to the next page in the table usually results in a long load time again

Environment

No response

Additional Context

I loaded a decent amount of fixtures data to a sandbox and deploying main at the time of this ticket (basically staging-135) had a long load time. However, deploying staging-124 to the same sandbox resulted in less than a second load time for navigating to the tables and applying filters/pagination etc.
