Today we are increasing the expiration interval for cached content from 1 hour to 2 hours, so that guest visitors to VMware Communities will see content that is up to 2 hours old. This change is expected to increase overall site performance because more visitors will see cached content, which is served faster than non-cached content and offloads traffic from the application. After the last Akamai change we made (caching site pages for guests), site visitors including both guests and logged-in visitors reported faster page load times on the site. Today's change is part of our on-going strategy to improve site performance on VMware Communities.
Please see Performance Upgrade Planned May 28 for a full explanation.
Great that you guys are actually working on this!
