Intel has released a report claiming Java performs better on Pentium than Sun Sparc, apparently in direct contradiction of a recent Microsoft-sponsored study, which came to the opposite conclusion.
The Microsoft study, (see VNU Newswire 7 February), indicated that the design of Intel?s floating point unit slowed down the way it processed Java.
But according to Intel?s document, the opposite is true. Two benchmarks were used to evaluate performance - 'PC Magazine' Labs? JMark 1.01 and Pendragon Software?s Caffeinemark. The JMark benchmark apparently showed that a 100MHz Pentium-based machine ran 0.9 times faster for a AWT graphics mix and up to 10.6 times faster for allocation and garbage collection than a Sparcstation 5.
The Caffeinemark test showed that a 100MHz Pentium box ran 10.5 times faster when processing logic and 17.4 times faster when dealing with graphics than a SparcStation 5.
Amy Porter, Javasoft?s European marketing manager, said: ?Intel can crow about these results for the next couple of months, but they won?t really matter when we come out with Hotspot. Java?s performance will be equal or better than compiled C++ and will be equally as fast on all platforms. But, it does lend credibility to Sun?s strategy of openness.?
She added that Hotspot, which uses mathematical algorithms to optimise the relevant part of an application when that part is being processed, will be available in version 1.2 of the Java Development kit, due to ship in a couple of months.
Hotspot, which Sun acquired when it purchased Longview Technologies, will also remove the need for a Just In Time (JIT) compiler. While JITs improve performance, users must compromise portability because they need to compile their Java applications for a specific platform.
