2. 2 P2P: An Enabling Technology Like many technology innovations, P2P is most powerful when combined with a compelling business need P2P is a new and better approach to solving certain business problems Porivo sells products powered by a P2P framework –Some key Internet problems can only be solved by a P2P approach

3. 3 The Problem: Poor Performance Poor online performance costs businesses $25 billion per year (Zona Research) 28% of attempted online purchases fail (BCG) Slow page performance is the primary reason for transaction abandonment –Business transactions are at particular risk “Eight seconds was kind of the threshold, but that’s a ridiculous notion now. The real expectations are around 4 seconds.” Forrester Research, Information Week

4. 4 Web Performance Measurement Companies purchase “Web Performance Measurement” services and tools to manage their online businesses –Performance data is used to diagnose problems and change infrastructure, content and design But current products provide incomplete data –Companies have resorted to guesswork to evaluate real user experience and impact Only Porivo offers true end-to-end Web performance testing –Porivo’s “peerReview” product enables fact-based decisions –Porivo is the only provider of true end-user testing, giving more accurate and meaningful data

7. 7 Porivo’s Unique Approach Porivo Network: 15,000+ registered machines at end- users homes or offices Geographically diverse clients in US (and over 50 countries) Techno-graphically diverse clients: dialup through T3 Data center monitoring: small number of “beacon” servers in data centers Complete Data: Only Porivo measures any URL to the end-user with data populations that allow valid, detailed analysis

8. 8 P2P Technology Model

9. 9 The Porivo PEER Users across the globe download the Porivo PEER application to join the testing network Carefully managed to provide a “representative slice” of the global Internet population Users can receive PayPal payments each month for availability and usage Flexible technology platform for future product development

10. 10 The Porivo Advantage This global testing network allows Porivo’s “peerReview” product to: –Measure the performance of Web sites from the user’s desktop –Capture “last mile” latencies –Measure the performance of complete transactions (e.g. buying a book) –Send automated alerts when performance falters

11. 11 Identify Site Problems Example: apple.com peerReview detected performance degradation Drill-down enables identification of root cause

12. 12 Identify Bottlenecks Object-level analysis finds content bottlenecks and configuration problems Example: askjeeves.com

13. 13 Raw Data Drill-down

14. 14 Thank You “Porivo stands out as a reliably accurate source for realistic measurements of the true user experience, largely because of two key factors: First, its agents are on real desktops that see the performance of the full path from the server. Second, it can tap the resources of thousands of agents distributed over demographic and geographic points that match the true Internet population.” Peter Sevcik Business Communications Review October 2001 Gordon Kass CEO & President gordon.kass@porivo.com Porivo Technologies, Inc. 2525 Meridian Parkway, Suite 240 Research Triangle Park, NC 27713 Register for a free appraisal of your Web site’s performance at: www.porivo.com
