Firefox 3.5 used the smallest amount of memory during its peak, it used the smallest amount of memory when all points were averaged, and it used the smallest amount of memory at the end of the experiment after all tabs were closed. Firefox 3.5 continues Firefox 3.0's legacy of being the most memory efficient browser in this style of experiment.

A noter le "in this kind of experiment". Le test en lui-même ne montre pas grand chose, il est biaisé initialement par le fait que Windows gère mal la mémoire dans le sens où il ne maximise pas l'utilisation de la RAM. La seule chose importante est de savoir si la mémoire utilisée est la RAM ou la mémoire virtuelle (ie. un bête fichier). Tant qu'on reste dans la RAM, il n'y a pas de problème, et de ce point de vue là, une utilisation par Chrome de 1Go de mémoire sur les 4Go de mémoire physique (configuration du test) n'est pas forcément négatif au niveau des performances. De même, si la faible consommation de mémoire de Firefox est due à un nettoyage aggressif des structures de données temporaires, ça peut être pénalisant en vitesse. Mais étant donné que ce test ne regarde que la mémoire (espace) et pas la vitesse (temps), les conclusions ne peuvent être que très limitées. La remarque sur IE8 ne fait pas très sérieux...

The Photos application is one of Facebook’s most popular features. Up to date, users have uploaded over 15 billion photos which makes Facebook the biggest photo sharing website. For each uploaded photo, Facebook generates and stores four images of different sizes, which translates to a total of 60 billion images and 1.5PB of storage. The current growth rate is 220 million new photos per week, which translates to 25TB of additional storage consumed weekly. At the peak there are 550,000 images served per second. These numbers pose a significant challenge for the Facebook photo storage infrastructure.

In the late 1980s, Japan was awash in seemingly unlimited wealth and rising toward what would be the peak of its modern economic success, power, and influence. In 1991 the same lethal combination of risky loans, inflated stocks, and real estate speculation that created this "bubble economy" caused it to burst, plunging the country into its worst recession since World War II.
