PANGORA (Lycos Europe) web software is built primarily using PHP server-side scripting language. To stay competitive, content heavy shopping portals demand top-notch response time to ensure optimal user experience at all times. Companies utilizing PANGORA's Shopping services generally require PANGORA to commit to page delivery of less than 2 seconds. Therefore PANGORA constantly aspires to finding new ways to decrease response time. Installing Zend Performance Suite to improve response time, decrease download time and increase server throughput made it possible for PANGORA to stand by their SLA (service level agreement) with their numerous customers. Dynamic Partial Page Caching The typical page of a shopping search incorporates both dynamic and static elements. For example, Lycos Shopping UK includes a "Top Products" feature that offers product rankings based on real-time hit-statistics. Although the database is updated with every user hit, the ranking is updated only once every 24 hours. Allowing Lycos to cache only the "Top Products" feature would save thousands of database hits allowing for more efficient use of resources.
