If you want to test OS performance and use Java programs in there to do so,
you would use the same Java version, wouldn't you? They didn't.
Linux: 1.6.0_0-b12
Solaris: 1.6.0_10-b33
FreeBSD: 1.6.0_07-b02
The important part is the _XX, not the -bYY. The bYY may be something
we don't care about, but the _XX part is something which may cause
performance differences.
Since system have their local patches (I know FreeBSD does), I don't
think it's even possible to test "exactly the same" version ;)
But this also goes into the "What OS ships with" category.
We don't ship with java at all... strictly speaking. ;)
If you want to run number crunching software, you are interested in high
computing throughput of your app, so you use a compiler which performs best
for your code in question (which would mean probably the Intel compiler or
the Portland compiler on Linux, maybe the Sun compiler on Solaris, and
probably gcc on FreeBSD). You also want to optimize the code for your CPU
(it makes a difference if you do floating point calculations and are allowed
to use the SSEx or whatever instructions), and not some generic settings the
OS comes with.
I think they went with the "stock" configurations as that's what
almost all users will use.
I fully agree. But number crunching (as benchmarked, and I'm not
talking about LAME which has a 2% difference) is not something almost
all users will do. Something the masses may do with the OS is not
covered at all, no browser tests, no interactivity (maybe with high
load in the background) tests. As I said, they don't even tell what
they want to test (and as such, everything we can do is speculate...
that's not something which will lead to interesting results in the
thread).
Bye,
Alexander.
