Sun's Project Tiger has matured and resulted in the release of the
JavaTM 2 Platform Standard Edition (J2SETM platform) Version
5.0, Beta 2. Accompanying the release was news of the latest benchmark results
for the solution, which show it as capable of delivering 59,648 JBB
operations per second on the SPECjbb 2000 on a 64-bit two-way system.
"Java technology has built a commanding lead in the network computing
arena with undisputed popularity and demand among developers," said
Jeff Jackson, vice president of Java Developer Platform and Strategy at
Sun. "With over 110 million downloads of J2SE since its availability in
December 1998, the Java platform continues to fuel the Java economy and
drive global business innovation on desktops and servers."
The SPECjbb 2000 benchmark results were achieved running JavaTM
Development Kit (JDKTM) 5.0 on a 2.4 GHz Sun FireTM V20z server,
based on AMD 64 Opteron processors. The 64-bit two-way system beat the
best previously announced 64-bit two-way system results by nine
percent. In addition, the tests indicate Sun has the capacity to
support more warehouses than any other two-way system, having
demonstrated the ability to support 80 warehouses -- 10 times the
number typically run on a two-way system.
The new J2SE 5.0 technology delivers more than 100 new features,
including language updates, generics, enumerated types, metadata and
autoboxing. Other performance improvements in the new release include
reduced startup time, a smaller memory footprint and auto-tuning to
deliver optimized performance on various computer systems right
The platform also features a new monitoring and management API that
enables tools to monitor the health of a running JavaTM virtual
machine (JVMTM)* remotely or for applications to perform self
monitoring for higher levels of reliability, availability and
serviceability. Also new in the J2SE 5.0 platform is the Java
Management Extensions (JMX) technology, which provides a simple,
standard way of managing Java resources such as applications, devices
In addition, the solution has been given an updated, more modern,
cross-platform look and feel. Support for advanced graphics hardware
acceleration via Sun OpenGLR enables higher levels of Java 2DTM API
performance, while a new Pack200 utility dramatically reduces the
download size of applets and applications for faster access. User
security has been simplified and modified to improve safety.
Sun reported that the JavaTM Specification Request will guide the
next platform release, which will include increasingly sophisticated
support for XML and Web Services, along with enhanced monitoring and
management features, building on J2SE 5.0 features. The team also is
evaluating features to simplify enterprise desktop development and
