Ubuntu, Kubuntu, Xubuntu "While 64-bit support is now considered common for both Intel and AMD processors, many Linux (as well as Windows) users are uncertain whether to use a 32-bit or 64-bit operating system with there being advantages for both paths. With this being the last Phoronix article for 2006, we decided to take this opportunity to look at the common question of whether to use 32-bit or 64-bit software. In this article, we will be comparing the i386 and x86_64 performance with Ubuntu 6.10 Edgy Eft and Ubuntu 7.04 Feisty Fawn Herd 1 to see how the numbers truly stack up."

Ridiculous conclusions.... Why?!?

The tested programs were 32 bits programs compiled in 64 bits... this does not change in any way the actual programming.

If you have a 8 bit algorithm, try building it up in 32 or 64 bits... it is still a 8 bit limited program with an 8 bit algorithm.

However, some applications can use and afford 64 bit programming... then you will find the performance more than doubled... (in the parts of the program that use that code). So we get a mix... that will be near the double or less...

Ity all depends of the data you process and the algorithm. Period.

Expecting magic is plain nonsense.
You get what you tested. If you do not do what you are doing or how things work... You get "amazing" results that only reveal your ignorance.

Sorry to be rude but "Articles" made of vapor deserve to be denounced as a bad service to all and the spread of trash. It dis-informs people. No-good... You'll agree.
