For very large sites, setting DNSLookup to 0 might be the only reasonable choice. DynamicDNSLookup allows to resolve host names for items shown in html tables only.
Our experience from processing a quite large site (http://meteo.pl) with 8-10 millions hits a day is positive. Typical "dynamic resolving" overhead never has exceeded few seconds.
