Hi @all, this is not a problem, and maybe it was already discussed (I don't follow the list permanantly), but I find it surprizing.
At 17:00 yesterday I changed from BIND 9.18 to 9.20. Now I counted the RRs processed for a specific activity, and there seem to be statistically significant differences: "2025-12-02 06:00:00+01" 927 "2025-12-02 07:00:00+01" 982 "2025-12-02 08:00:00+01" 543 "2025-12-02 09:00:00+01" 369 "2025-12-02 10:00:00+01" 570 "2025-12-02 11:00:00+01" 389 "2025-12-02 12:00:00+01" 1050 "2025-12-02 13:00:00+01" 375 "2025-12-02 14:00:00+01" 390 "2025-12-02 15:00:00+01" 420 "2025-12-02 16:00:00+01" 1056 9.18 "2025-12-02 17:00:00+01" 1840 --- "2025-12-02 18:00:00+01" 1304 9.20 "2025-12-02 19:00:00+01" 1191 "2025-12-02 20:00:00+01" 1158 "2025-12-02 21:00:00+01" 1230 "2025-12-02 22:00:00+01" 1182 "2025-12-02 23:00:00+01" 1152 "2025-12-03 00:00:00+01" 1231 "2025-12-03 01:00:00+01" 1311 -- Visit https://lists.isc.org/mailman/listinfo/bind-users to unsubscribe from this list.
