The performance was greatly improved by removing two N+1 queries issues for each endpoint. For comparison: 1. `GET /projects/:id/members` With two N+1 queries issues (one was already fxed in the following snippet): ``` ProjectMember Load (0.2ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN ('ProjectMember') AND "members"."source_id" = $2 AND "members"."source_type" = $3 AND "members"."type" IN ('ProjectMember') AND "members"."requested_at" IS NULL ORDER BY "members"."id" DESC [["source_type", "Project"], ["source_id", 1], ["source_type", "Project"]] User Load (0.5ms) SELECT "users".* FROM "users" WHERE "users"."id" IN (5, 22, 16, 13) ORDER BY "users"."id" DESC ActiveRecord::SchemaMigration Load (0.2ms) SELECT "schema_migrations".* FROM "schema_migrations" ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN ('ProjectMember') AND "members"."source_id" = $2 AND "members"."source_type" = $3 AND "members"."type" IN ('ProjectMember') AND "members"."requested_at" IS NULL AND "members"."user_id" = $4 ORDER BY "members"."id" DESC LIMIT 1 [["source_type", "Project"], ["source_id", 1], ["source_type", "Project"], ["user_id", 5]] ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN ('ProjectMember') AND "members"."source_id" = $2 AND "members"."source_type" = $3 AND "members"."type" IN ('ProjectMember') AND "members"."requested_at" IS NULL AND "members"."user_id" = $4 ORDER BY "members"."id" DESC LIMIT 1 [["source_type", "Project"], ["source_id", 1], ["source_type", "Project"], ["user_id", 22]] ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN

"members"."id" DESC LIMIT 1 [["source_type", "Project"], ["source_id", 1], ["source_type", "Project"], ["user_id", 16]] ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE

Without the N+1 queries issues: ``` ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN ('ProjectMember') AND "members"."source_id" = $2 AND "members"."source_type" = $3 AND "members"."type" IN ('ProjectMember') AND "members"."requested_at" IS NULL ORDER BY "members"."id" DESC LIMIT 20 OFFSET 0 [["source_type", "Project"], ["source_id", 1], ["source_type", "Project"]] User Load (0.5ms) SELECT "users".* FROM "users" WHERE "users"."id" IN (5, 22, 16, 13) ORDER BY "users"."id" DESC ``` 2. `GET /projects/:id/access_requests` With two N+1 queries issues: ``` ProjectMember Load (0.3ms) SELECT "members".* FROM "members" WHERE "members"."source_type" = $1 AND "members"."type" IN
