11. Performance & Scalability • Performance & scalability are similar - but not the same! • Performance • That which affects the response time of your system to requests from a single user at a time • Scalability • The ability of your system to maintain the same response times as the number of users increase

13. Component Architecture • Dynamai protects against peak loads even for dynamically generated web pages. • PSE plug-in provides load balancing and transparent failover support for SE requests • Servlet Engine and EJB Server run in the same process to reduce communication lag • Efficient native connections to databases Dynamai Dynamic Web Cache HTTP Apache Web Server PSE plug-in HTTP or PSE native protocol PowerTier Servlet Engine PowerTier EJB Server Native DB protocol or JDBC Database
