These are the questions we wanted to answer, so we asked Dell to provide us with a high-spec machine to give all the operating systems room to perform to their max. Our test machine packed an Intel Core i7 920, which in layman's terms has four cores running at 2.67GHz with hyperthreading and 8MB of L3 cache. It also had 6GB of RAM, plus two 500GB of hard drives with 16MB of cache.
The tests we wanted to perform for each operating system were:
- How long does each operating system take to install?
- How much disk space was used in the standard install?
- How long does boot up and shutdown take?
- How long does it take to copy files from USB to HD, and from HD to HD?
- How fast can it execute the Richards benchmark?
Before we jump into the results, there are a few things we should make clear:
- To ensure absolute fairness, install time was measured from the moment the computer was turned on until we reached a working desktop.
- The same computer hardware was used for all tests, and all operating systems were installed fresh for this article.
- We used the Ultimate versions of Windows Vista and Windows 7, simply because Windows 7 was provided only in this flavour.
- We used the Windows Vista SP1 disk to accurately reflect what users are likely to experience todaay.
- Our Windows 7 version is the open beta that Microsoft issued recently. It is probable Windows 7 will be at least this fast in the final build, if not faster.
- For Ubuntu 9.04 we used the daily build from January 22nd.
- All operating systems were installed using standard options; nothing was changed.
- After checking how much space was used during the initial install, each operating system was updated with all available patches before any other tests were performed.
- Our journalistic friends have informed us that Windows Vista (and, presumably, Windows 7 too) has technology to increase the speed of the system over time as it learns to cache programs intelligently. It also allows users to use flash drives to act as temporary storage to boost speed further. None of our tests are likely to show this technology in action, so please take that into account when reading the results.
- The filesystem, boot, shutdown and Richards benchmarks were performed three times each then averaged.
Install time
Amount of time taken to install, from machine being turned on to working desktop. Measured in seconds; less is better.
At first glance, you might think that Ubuntu clearly installs far faster than either version of Windows, and while that's true there is one important mitigation: both Windows Vista and Windows 7 run system benchmarks part-way through the installation to determine the computer's capabilities. A bit of a flippant one - just how many mouse clicks does it take to install an OS with the default options?
Surprisingly, Ubuntu 8.10 gets it done with half the clicks of Windows 7. NB: hopefully it's clear this doesn't make Ubuntu 8.04 twice as easy to install. Measured in, er, mouse clicks; fewer is better. Disk space used immediately after a fresh install. Measured in gigabytes; less is better.
While some people might complain that we used the Ultimate editions of both Vista and Windows 7, they probably forget that the standard Ubuntu includes software such as an office suite as standard. NB: Vista failed to detect the network card during install, leaving us without an internet connection until a driver was downloaded on another computer.Bootup and shutdown
Boot up time was also measured from the moment the machine was turned on, and the timer was stopped as soon as the desktop was reached. The Dell box does take about 20 seconds to get past POST, but to avoid questions about when to start the timer we just started it as soon as the power button was pressed. Amount of time taken to boot, from machine being turned on to working desktop. Measured in seconds; less is better.
The 32-bit version of Windows 7 is the only one to beat the one-minute mark, but that advantage is quickly lost in the switch to 64-bit. Linux has always been rather slow to boot, but as we understand it reducing boot time is one of the goals of the Ubuntu 9.04 release. Amount of time taken to shutdown, from button being clicked to machine powering off. Measured in seconds; less is better.
Windows lags a little behind the Linuxes, with 64-bit again proving a sticking point - this time for Windows Vista.
