I can't remember which browser I performed this specific test in, but the results for each configuration were the same - the DNS was resolved right after the HTML document completed.

without prefetch
with prefetch

Notes:
I am prefetching for ghost.redstorm.com, rainbow.redstorm.com, ajax.googleapis.com, and http://www.google-analytics.com.

It's not much of a performance gain, but it is one. And it was easy. Smile

pyronite - Can you please specify with which browser these tests were done?
