When analysing traffic on Projects List API endpoint, we realised the huge amount of it is anonymous traffic. Here are the statistics for January 8th: - total requests: 2,597,483 - requests from anonymous users: 1,063,508 (https://log.gprd.gitlab.net/goto/d329ba00-91c7-11ed-85ed-e7557b0a598c) - slow requests: 115,429 - slow requests from anonymous users: 37,518 (https://log.gprd.gitlab.net/goto/b1b211b0-91c7-11ed-9f43-e3784d7fe3ca) Most of the slow queries is using 100 per_page param, making it that harder to produce better times. I propose rate-limiting this endpoint for anonymous users - heavily. I don't know how to get to the right limit for that, I will ask @reprazent and SREs for advice here.
