Ubuntu: 32-bit v. 64-bit Performance

Filed under
Ubuntu

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 this 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.

One of the common (and leading) reasons for 64-bit processor owners continuing to use 32-bit software is due to some software not being available for x86_64 Linux. The key package that keeps many Linux users to running i386 software is for Macromedia Flash Player support (though 32-bit Firefox on 64-bit Linux fixes that issue or using Gnash). Linux provides backward compatibility for running 32-bit executables and most open-source software can easily be compiled for x86_64.

Both i386 and x86_64 versions of Ubuntu 6.10 Edgy Eft and Ubuntu 7.04 Feisty Fawn Herd 1 were used for testing. An AMD Athlon 64 X2 processor was selected for comparing the 32-bit and 64-bit performance of both Ubuntu Linux builds. Below is a list of all the hardware used for testing as well as the major software versions. The ATI Radeon X300SE was used with the open-source R300 Radeon drivers and the options set were AccelMethod: XAA, AccelDFS: 1, GARTSize: 64, EnablePageFlip: 1, and ColorTiling: 1.

  • The Linux Migration: April 2017 Progress Report
    In December 2016, I kicked off a migration to Linux (from OS X) as my primary laptop OS. In the nearly 4 months since the initial progress report, I’ve published a series of articles providing updates on things like which Linux distribution I selected, how I’m handling running VMs on my Linux laptop, and integration with corporate collaboration systems (here, here, and here). I thought that these “along the way” posts would be sufficient to keep readers informed, but I’ve had a couple of requests in the last week about how the migration is going. This post will help answer that question by summarizing what’s happened so far. Let me start by saying that I am actively using a Linux-powered laptop as my primary laptop right now, and I have been doing so since early February. All the posts I’ve published so far have been updates of how things are going “in production,” so to speak. The following sections describe my current, active environment.

Lumina Desktop Gets lumina-mediaplayer

  • 1.3.0 Development Preview: lumina-mediaplayer
  • Lumina Desktop Gets Its Own Media Player
    There's now yet another open-source media player, but this time focused on the BSD-focused Qt-powered Lumina Desktop Environment. Lumina Media Player is one of the new additions for the upcoming Lumina 1.3. Lumina Media Player's UI is quite simple so far and allows playing of local audio/video files along with basic audio streaming -- currently implemented for Pandora.
