As a follow up to my previous post I have decided to re-run the tests, this time with the updated distributions (where available of course). Again I will be testing all of this within VirtualBox on ‘machines’ with the following specifications:
- Total RAM: 512MB
- Hard drive: 8GB
- CPU type: x86
The tests were all done using VirtualBox 3.2.6 on Windows, and I did not install VirtualBox tools (although some distributions may have shipped with them). I also left the screen resolution at the default 800×600 and accepted the installation defaults. All tests were run on July 3rd, 2010 so your results may not be identical.
As before I have provide state of the art graphs for your enjoyment.
First boot memory (RAM) usage
This test was measured on the first startup after finishing a fresh install.
This test was performed after all updates were installed and a reboot was performed.
The net growth or decline in RAM usage after applying all of the updates
The hard drive space used by the distribution after applying all of the updates.
As before I’m going to leave you to drawing your own conclusions. I will point out though that almost all of the distributions have done a good job of lowering memory usage with system updates, which is very commendable. Also it’s important to note that even though RAM and disk space increase with updates so might performance so it’s all about which metric you hold as most important.
Previously I was running KDE 4.3.3 on top of Fedora 11 (for the first experiment) and KDE 4.6.5 on top of Gentoo (for the second experiment).
