There are two issues which affect DNS lookups. One is - disable IPV6. The
second is that some DNS servers seem to miss the first couple of requests
from Linux machines. The default timeout is five seconds, so this
frequently results in about a 10-12 second time lag (the IPV6 lag can be
about 30 seconds). To fix this issue, add

option timeout:1

to the /etc/resolv.conf file.
