Re: suggetsed distro for Bind

I’m not sure if a container will pass through the CPU instruction set 
required to leverage hardware acceleration on newer (or even not-so-new) 
Intel processors. In KVM, for example, you have to enable it explicitly.

One way to check for supported instructions is:

grep -o -w 'aes\|sha_ni\|pclmulqdq\|rdseed\|rdrand\|avx\|avx2\|avx512' 
/proc/cpuinfo | sort | uniq

Hardware acceleration can be beneficial if you’re running a resolver 
that performs a lot of DNSSEC validation—SHA_NI in particular can speed 
up operations involving DS/NSEC/NSEC3 records. That said, if you’re only 
running an authoritative server or a small-scale resolver, crypto 
acceleration may not be critical.

Fwiw, my preferred distro for running BIND9 is Debian 12—it includes 
dnstap support out of the box.
