Greetings folks, I came across this pretty strange testbed which compares Java and C++ performance on <a href="http://www.developer.com/java/article.php/ 3856906/Java-vs-C-The-Performance-Showdown.htm"> Gamelan.com</a> and promoted by a Java/Open Source Daily newsletter, from Gamelan which I supposed should promotes Java and Open Source despite a lot of Microsoft ads ;-)
The testbed claims to show that C++ is 25,000 times faster than Java. >From what I know about the JVM, I was expecting C++ to be at most 5 to 10 times faster. Am I wrong? Maybe the C++ compiler/optimizer had removed dead code from the testbed. Furthermore, in order to perform as fast as stated, the computer should run over 20 Ghz ??? Furthermore, some readers have carefully observed, in order to ensure such a performance, the computer should run at over 20 GHz. What do you think about this so-called testbed? Are there any good benchmarks comparing C and Java? Thanks
