Each DNS query consists of at least two UDP packets, one query and one
response. If your DNS server is doing searches (not using a forwarder)
then some queries may result is a few additional queries (one or two) to
find the correct DNS server to ask.

DNS isn't usually a lot of traffic in packets or bytes, not compared to
HTTP or other data transfer protocols anyway.

If you have a slow saturated link then long service times for DNS
queries is normal. (long service time for any type of requests on a slow
saturated link is normal).
