Performance & ScalabilityPerformance & Scalability

Performance & scalability are similar - but not Performance & scalability are similar - but not the same!the same!

PerformancePerformance– That which affects the response time of your

system to requests from a single user at a time

ScalabilityScalability– The ability of your system to maintain the

same response times as the number of users increase

• 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
