Sun has been accused of cheating in tests of its Java compiler.Pendragon Software, the developer of the widely used CaffeineMark Java performance benchmark, claimed last week that Sun's new Just In Time (JIT) Java compiler produces a "misleading score" by including part of the benchmark code. Sun claimed that the JIT compiler makes Java applications run 50% faster on Sun's Solaris operating system than on Windows NT. But the creators of the benchmark refute that claim. In one of the nine modules that constitute the CaffeineMark test, the Solaris JIT compiler was 50 times faster than any system to date. This aroused Pendragon's suspicion, the company said. The developers slightly modified the test, after which all other Java environments produced similar results but Sun Solaris was suddenly 300 times slower. Ivan Philips, president of Pendragon Software, issued a statement requesting that Sun should retract the claim. "Though we made a request, no retraction of the original press release was issued by Sun Microsystems, so we felt it would be fair to all Java technology vendors to set the record straight," he said. "The fastest overall CaffeineMark 3.0 scores we have seen to date are from Windows NT systems running on Intel Pentium II processors at 300MHz." Sun responded in a statement claiming the allegations had been stirred up by Microsoft. "Sun blew the doors off the CaffeineMark 3.0 benchmark, beating NT by 50%, " said a spokesman. "Now Microsoft has gone whining to Pendragon about being beaten. Too bad. We optimised the product to deliver better performance than the competition."
