I don't know that this theory totally holds water (Windows OS developer here, announcing obvious bias) - looking at the results, the one place Windows really gets nailed is the I/O test; I suspect there's some significant optimizations that could be done there, as I/O on Windows OS in general certainly isn't 4x slower than Linux.
- headius 16y agoIf there's something we or the JVM could do to improve these numbers, I would love to talk to you about it. At this point, if the JVM developers haven't found the magic sauce, we JRuby guys probably won't either...but I'd really love for JRuby performance on Windows to match JRuby performance on Linux.
- xpaulbettsx 16y agoI don't think that I can actively hack on the JVM, but I can tell you that XPerf is a great way to determine where you're spending your time. http://www.microsoftpdc.com/2009/CL16 http://www.microsoftpdc.com/2009/CL16 is a really good intro video on the topic, it's a very powerful tool (though doesn't provide as much analysis as Instruments for example)
