Performance enhancements
EAServer 4.0 includes the following features to improve application
performance.
JDK 1.3 and Hotspot VM integration
For improved performance, EAServer 4.0 can run with JDK 1.3 and the Java
Hotspot virtual machine. On some platforms, EAServer can also use the Java
Hotspot VM with JDK 1.2. The server JDK is determined by the command-line
syntax that you use to start the server. For details, see Chapter 3, “Creating and
Configuring Servers,” in the EAServer System Administration Guide.
Servlet response caching
EAServer 4.0 includes a servlet response cache to improve response times for
Web clients. When page caching is enabled for a servlet or JSP, EAServer
checks the cache before invoking the servlet. If an appropriate response is
found in the cache, EAServer returns the contents of the cache, instead of
calling the servlet. If a response is not found in the cache, EAServer invokes
the servlet, then saves the response and the response headers in the cache.
