Why are you using nslookup instead of dig? The latter tool will
actually tell you how long the lookup took.

I think you need to investigate the problem that's causing the 2-second
delay in the first place. That's not normal if you have a decent
Internet connection.
Most domains have cache TTLs between 1 hour and 1 day, so 10-30 minute
timeouts is also unusual.
