Scope: Performing an A lookup (most common use case).
When resolving through DoT and TCP,
phuslu/fastdns is between 2x and 4x
faster than both miekg/dns and stdlib. When it comes
to UDP resolutions, all packages are more or less equivalent with
phuslu/fastdns being fractionally faster. In all cases, miekg/dns is
fractionally faster than stdlib.
When it comes memory usage, phuslu/fastdns is extremely efficient in all cases
while miekg/dns and std have comparable usage.
