By minifying OPML files you will shave some precious time off the page load speed of your website. Now we're not talking about cutting your page load speed by half or something, but every little bit helps when it comes to your website loading.
Not only is it important for first time visitors how good your site loads are, but it is also important to shift the search engine rankings. If you want faster page load times and better rating scores, you want to minify alll other asset files as well.

This file type transfers subscription information for RSS Feeds between programs that can manage and display RSS Feeds. This protocol is currently widely used to exchange web feed aggregator lists like RSS aggregators.
It is primarily used to share lists of RSS feeds, podcast subscriptions, and reading lists between applications. It is also used to create and share outlines and structured lists.
