StumbleUpon is going with a new content delivery network – NetDNA’s MaxCDN. This, according to the two parties involved, will help increase web page download speed on StumbleUpon.com.

“The social media market is crowded, therefore it is imperative that we provide our users with an experience that is superior to all other discovery engines,” said Anoakie Turner, software architect for StumbleUpon. “MaxCDN allows us to do just that and we are incredibly pleased with the performance we’ve achieved to this point.”

“With more than 25 million users worldwide, StumbleUpon was in need of a web performance optimization solution that scales worldwide,” said Samir Said, vice president of MaxCDN sales. “It is an honor to be selected by StumbleUpon and we look forward to a successful relationship with the company.”

Last year, StumbleUpon placed more of an emphasis on its own site as a content destination discovery. Historically, StumbleUpon has been mainly about pointing you to content on other sites, with little need to visit StumbleUpon.com itself.

To a major extent, it’s still about pointing you other pages on other sites, but with the recent redesign, there is more of a reason to stick around on StumbleUpon’s own site to at least browse thumbnails, channels, and other users’ profiles before selecting the content you want to venture to.

Despite these changes, the site is still a major traffic driver to sites all over the web.
