Howdy, >From "Java theory and practice: Urban performance legends" >(http://www-106.ibm.com/developerworks/library/j-jtp04223.html?ca=dnt-4 16):
I'd read that when it was posted: it's a good and interesting article. Thank you for sending the link anyways. I agree with many of the points made in the article. >It's difficult to say why you're getting the results you're getting w/ out >seeing the benchmark code. But as the above paragraph states, even w/ your I tried attaching it as a .java file. I'll try again as a jar file which contains the bytecode, source code, my system info, my JDK info, and sample results. >code, it'd be tough to say for sure why the graph is the way it is w/out >seeing the bytecode your particular compiler is generating and knowing the >details of the way the particular JVM you're using dynamically converts >the bytecode to native code. I agree. So how would I ago about answering this "why" question? Namely, "why is FastHashMap writing faster than java.util.HashMap writing?" >This isn't to say that the results aren't interesting, they're just not >horribly meaningful on their own. It'd be interesting to see the code and >see the results of running the benchmark under a profiler to see where >time was actually being spent, and running more than just 10 runs per >object type. I agree with both. I will also run it on different operating systems to see if the behavior is consistent. I will post more information as time permits.
