Benchmarked: Ubuntu vs Vista vs Windows 7 | TuxRadar
In depth: A lot of people have been chattering about the improvements Windows 7 brings for Windows users, but how does it compare to Ubuntu in real-world tests? We put Ubuntu 8.10, Windows Vista and Windows 7 through their paces in both 32-bit and 64-bit tests to see just how well Ubuntu faces the new contender. And, just for luck, we threw in a few tests using Jaunty Jackalope with ext4.
When Windows users say that Windows 7 is easier to install than ever, what do they really mean? When they say it's faster, is it just in their heads, or is Microsoft really making big strides forward? And, perhaps most importantly, when Linux benchmarkers show us how screamingly fast ext4 is compared to ext3, how well do those figures actually transfer to end users?
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?
We also, just for the heck of it, kept track of how many mouse clicks it took to install each OS.
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.
And, of course, there's the most important proviso of all: it is very, very likely that a few tweaks to any of these operating systems could have made a big difference to these results, but we're not too interested in that - these results reflect what you get you install a plain vanilla OS, like most users do.
I didn't think of the sidebar gadgets, i thought you were speaking of something else, not remembering they are called like that.
