Based on the findings in T177641: Enable AbuseFilter per-filter profiling on Portuguese Wikipedia & monitor if there is a performance impact (specifically in comment T177641#3713701) we found no noticeable performance impact for 75p but a potential bump for 99p.
This ticket is to re-enable the per-filter profiling and monitoring (in the same way as monitored and evaluated for PTWP) if there is a performance impact. If there is no impact, we will leave the profiling enabled. If there is a noticeable impact (exact amount TBD, pending discussion) then the profiling will be disabled again.
