What is windows server 2019 standalone DNS server request/sec

Below link gives the performance of DNS on windows server 2003, which says DNS server can support 9500 requests/second.

https://docs.microsoft.com/en-us/previous-versions/windows/it-pro/windows-server-2003/cc778608(v=ws.10)?redirectedfrom=MSDN

I am not able to get any documentation that gives the details of how many request / second are supported by windows server 2012, 2016 or 2019 standalone DNS server.
We are planning to migrate to DNS on windows server 2019 , appreciate if I can get the help regarding this dimensioning part.

Hi,

Thanks for posting in Q&A platform.

Regarding of how many request/sec are supported by windows server 2012, 2016 or 2019 standalone DNS server, there is no such official document to talk about this. The performance of the DNS server depends on lots of factors, such as DNS server hardware configurations, the server's processor, numbers of processors, memory, how do we configure the DNS server and so one. Every DNS server is configured differently, it's hard to say the how many requests can by handled by DNS server every second. The performance of the latest version Windows server is optimized than the old version, we would suggest our customer use Windows server with the latest version.

Best Regards,
Sunny
