In dealing with pre-cached data in any provider its really less of an issue for the provider than it is an issue with koop-pgcache and optimizations there (ie query performance / optimization). Just saying there are two sides to explore, the provider, which you done via the PR and the caching and retrieval of large data.

@dmfenton if it makes sense, but I think first I'd like to understand what the short comings of the current solution are in terms of benchmarks or just timed request numbers and whether its a cache issue or a provider issue or even a koop issue.
Can you provide references to a URL in koop that exhibits behavior that is "slow"?

@dmfenton so explain what happened here?
In the last test is returned in 1.7 seconds, so it was less than your 2 limit? :)

The basic FeatureServer request, which doesn't need to return any data is taking 1.7 seconds. Seems pretty long.
The other requests timeout even when I set the limit to 30 seconds.

This works but performance could be a lot better. Still, closing.
