32bit vs 64bit Linux performance
Filed in archive Misc by Rom Feria on December 30, 2006

Looking over the results 64-bit Ubuntu was able to provide a strong advantage in the GCC benchmarks with both LAME and the Linux 2.6.19 kernel compilation. However, a slight advantage had remained with both Unreal Tournament 2004 and the LAME encoding tests in a 32-bit environment. Outside of the i386 and x86_64 analysis, it is also worth noting that at this time there are no real speed increases between Edgy Eft and Feisty fawn; however, this was only the first Alpha (Herd) release of many to come before the April 2007 release of Ubuntu 7.04.
It will probably take around 3-6 months before Linux can be 64-bit optimized by default. However, it will be up to applications to drive the demand for the underlying operating system to take full advantage of the 64-bit architecture.
The question is -- is now the right time to invest in 64-bit processors when 32-bit processors are becoming cheaper? Will better processors become more affordable once applications natively support 64-bit processors?
