Hi @shailesh-google ,

Thank you for this pagination patch, which I just gave a try. As a test, I have a local site with drupal/apigee_edge:3.0.13 which is configured to fetch ALL the Apigee-related data for the /teams page from a local endpoint (to eliminate both the network latency AND the time Apigee Edge/OPDK would need to collect and return the data), with some 10k (!) teams.

• With both this and PR#1210 applied, first 1k of the 10k /teams page load time: 5.1/3.2 secs
• With both this and PR#1210 applied AND a custom patch (that uses the NullBackend for TeamStorage's cache) also applied, first 1k of the 10k /teams page load time: 2.6/1.4 secs

Also worth noting that while this pagination does decrease the page load times quite a bit, it also removes the possibility to find a particular team by (part of) its name using the browser's find-in-page functionality, as one might have to paginate thru quite a bunch of pages until the correct team is found. The situation is a bit better if the user knows the WHOLE name of the team (or searches for the first part of it), as it's still possible to order this list by the teams' name or status.

To mitigate this, it would be nice to have Views support for listing teams, so the sitebuilder could add some exposed filters as needed.
