Ubuntu 9.04: 32-bit vs 64-bit benchmarks

Filed under
Ubuntu

Most Linux users run a 32-bit distro, and many of them run a 32-bit distro on a 64-bit computer. The question is, why? We put 32-bit Ubuntu 9.04 head-to-head with its 64-bit counterpart to see what difference it really makes, and whether old compatibility worries are justified.

Thanks to extensive testing and feedback from the community, 64-bit Linux is as stable as 32-bit Linux, so there's little reason not to use it unless you have a need for a specific, 32-bit only app. Even Wine happily supports 32-bit Windows apps such as Microsoft Office or Half-Life 2 running on a 64-bit Linux installation, and cross-platform mainstays such as VMware, VirtualBox and Java have already been ported.

Why bother?
Of course, the other side of the coin is "if it's just as good for most users, why should 64-bit be used at all?" And the answer to that is "performance".

Contain yourself: The layman's guide to Docker

Welcome to the age of containerization, where an ecosystem led by startup Docker is leading IT organizations to ineffable peaks of efficiency, helping them scale their workloads ever-higher, and probably baking them a nice cake to boot (it's my birthday, I have cake on the brain, sue me). Microsoft, Google and Amazon Web Services are all tripping over themselves to make sure prospective customers know that their clouds are the place to be if you want to get the most from Docker.
