[17:42:51] <Amir1>	 SFS is slow :( https://performance.wikimedia.org/excimer/profile/70c8903135703a38
[18:13:18] <Krinkle>	 SFS is in prod?
[18:13:43] <Krinkle>	 I guess it's in warning/log-only mode or something?
[19:44:58] <legoktm>	 the trace shows IPSet as being slow, I don't think it was designed for such a large IP list
[19:51:36] <Krinkle>	 AtEase doesn't help either
[19:55:34] <Krinkle>	 the overhead is repeatable, given a wiki with SFS enabled: https://performance.wikimedia.org/excimer/profile/fa071caeb44b3a35
