the benchmark is pretty much irrelevant, because if it was we would all be coding in C or Fortran, or why not machine code or assembly ? On the other hand I find that the mono project (young, open source implementation ), is doing quite great against java 7 (commercial implementation, unless I misread). It would be interesting to see how the openJDK is performing ? (the real question would be : is openJDK crippled compared to the Oracle - JDK ?)

The point being debated is that the JVM is being developed and advanced more rapidly than the CLR. Performance is one way to demonstrate this. Performance does matter in many cases, and most folks aren't prepared to write their web services in Fortran.

I would hardly classify 7x slower as "quite great"

OpenJDK runs HotSpot, so no major difference

>>I would hardly classify 7x slower as "quite great"<< When half of that difference comes from running GC on a separate core, and we know that GC has not been tuned - perhaps we should call that particular difference accidental ;-)

Single core result Java still 3x faster than C#: http://shootout.alioth.debian.org/u64/benchmark.php?test=all...

Yes, and now look at the second half of my comment -- "and we know that GC has not been tuned" :-)

Start off with a different initial and maximum heap size (or a different GC option!) and the results may be different.
