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.

2014: The Open Source Tipping Point

2014 was a tipping point where companies decided there was too much software to write for any one company to do it by themselves. They are shedding commodity software R&D by investing in “external R&D” with open source. Those who master the game have a compelling advantage. Those who don’t are getting left behind. We are experiencing an innovation renaissance that is largely driven by open source software that powers distributed, scale out systems. It’s been a pleasure to see this trend develop this year and I’m looking forward to 2015 with anticipation. Read more

KDAB contributions to Qt 5.4

Qt 5.4 was released just last week! The new release comes right on schedule (following the 6-months development cycle of the Qt 5 series), and brings a huge number of new features. KDAB engineers have contributed lots of code to Qt during the last few months. Once more, KDAB is the second largest contributor to Qt (the first being The Qt Company itself). The commit stream has been constant, as you can see in this graph showing the last 16 weeks. Read more

Git 2.2.1 Released To Fix Critical Security Issue

Today's Git vulnerability affects those using the Git client on case-insensitive file-systems. On case-insensitive platforms like Windows and OS X, committing to .Git/config could overwrite the user's .git/config and could lead to arbitrary code execution. Fortunately with most Phoronix readers out there running Linux, this isn't an issue thanks to case-sensitive file-systems. Read more

Ubuntu 15.04 Alpha 1 For Its Various Flavors

While Ubuntu itself no longer puts out alpha/beta releases in favor of just testing out the daily Live ISOs, the various Ubuntu flavors still participating in the traditional release process have done their first alpha releases this afternoon for Ubuntu 15.04. Read more
