With the addition of new query param (i.e. requested_fields=profile_image) to discussion API GET endpoints for thread and comment; the discussion APIs got exposed to the possibility of performance degradation because this new param fetches and prepares the profile image related data of all the users that are participating in thread or comment.

We have gathered and compared two sets of load test results. The former results (i.e. with profile_image) are run on the latest changes and the later are run on older implementation (i.e. without profile_image).

There appears to be anomaly in the results below (highlighted 99%) where the new implementation is faster than the old. Where as, for other results the percentile of new implementation increases significantly with the increase in load. For example, the first pair of results where no. of clients = 48, the difference is in tens or hundrend and for the last pair of results where no. of clients = 610, the difference is in thousands.

Logically; there should only be increase in response time for GET endpoints, but we see in results that all other endpoints show differences too. This is because all PATCH, POST and DELETE endpoints first call GET endpoint to retrieve an 'id' of thread and/or comment and then make further processing on it.

New Relic:

Here is the new relic permaLink_without_profile and permaLink_with_profile where the average rpm for former is 1.55k and for later is 1.48k and 84.5% of requests are made for AccountViewSet.list (i.e. user accounts API for multiple usernames) for later.
