It's probably because it's waiting on ypbind. Once ypbind is killed
nsswitch only uses local files again.

it's normal on loopback I think, checksums are not computed on loopback.
You can try:
sysctl -w net.inet.ip.do_loopback_cksum=1
sysctl -w net.inet.tcp.do_loopback_cksum=1
sysctl -w net.inet.udp.do_loopback_cksum=1
