Prefetching DNS when hovering links

October 26th, 2012

Speed is sexy, and today Opera just got sexier.

When a user hovers links, they are likely to click them. To get the destination page to the user faster, Opera will now make DNS look-ups for the links when the user moves the mouse cursor ontop of the link. This will result in the destination page loading faster if the user decides to click on the link. Opera will not prefetch the destination resource/document, but only the domain name look-up.

DNS will only be resolved for HTTP links, and Opera will perform no more than five look-ups per second.

In addition there are a nice set of bug fixes included. So have a good testing weekend!
