Ubuntu 64-bit More Competitive Against Mac OS X

[bugmenot]

cool but the current osx version is 10.5.7

I think if the graphics and SQLite performance were fixed then there really wouldn't be much of a performance gap for most desktop users to care about.

There isn't any gap in SQLite. If you switch to Ext 4 you should see a huge improvement in this test. In real world benchmarks OS X doesn't have a chance with any of Big Three (Linux, FreeBSD, Solaris). An only area where OS X is better is graphics, but probably only when you don't use binary blobs on Linux (however 2D performance should still be better on OS X).

Lies, damned lies, and the statistics:

Seven of the 29 tests changed their winner/loser status for Ubuntu by switching from 32 to 64-bit. Six tests became winners for Ubuntu 64 and 1 became a loser.

Overall,

12 wins for Mac OS X,
4 wins for Ubuntu 32, and
13 wins for Ubuntu 64.

Ubuntu 64 wins.

Thanks good article! Really intressting...most ppl say there is no use in 64bit OS, only that it can use more RAM. Atleast I can point at something when I say it does perform better.

The major difference (which these benchs show) is the use of SSE by default in x86_64, which is way faster than x87 floating point unit.

Thanks VERY much for next Ext3 benchmark... Who's interested in Ext4?

About this 'regression' fixed in 2.6.29. Regression is probably in GCC or in some library (maybe this also explains why *BSD and Open Solaris aren't performance monsters in PB) and there's only workaround in 2.6.29. If there was regression in Linux kernel many people will complain about it and Linux devs test kernel themselves. If there's even only 2% performance drop they take care of this.
