Hello,
How do we minimize answers-slow, We are running on CentOS Linux release 7.9.2009 (Core)on VM with 4VCPUs and 16GB RAM. 
rec_control get-all | grep answeranswers-slow    80903answers0-1      598471answers1-10     1057756answers10-100   2342082answers100-1000 1341675auth4-answers-slow      119250auth4-answers0-1        61649auth4-answers1-10       1423348auth4-answers10-100     3095598auth4-answers100-1000   1515725auth6-answers-slow      0auth6-answers0-1        0auth6-answers1-10       0auth6-answers10-100     0auth6-answers100-1000   0noerror-answers 16875858nxdomain-answers        2726842servfail-answers        1780021
Are there any parameters that needs to enabled in recursor.conf so that the performance of DNS queries can be further improved.
Best Regards,
