If i have Dns Client service running, is it necessary to enable dns prefetch in the about:config section?

I've been wondering this for a while and can't seem to find the answer. Whenever i set network.dns.disablePrefetch to true, the browser seems to load a bit more smoothly and even with the pref. disabled, the dns client service seems to still cache dns whenever i check on cmd using the ipconfig /displaydns command. Does this mean that the browser still fetches dns even with the pref disabled?

From your description, I got the thought that the prefetech do not help to improve the speed.

I'm not really sure if it speeds up the loading process or not since it's a bit hard to tell but like i said, the loading is smoother. Is Dns Client service different from Dns prefetch?
