a tiny map of the worldThis is an enormous amount of geographic data. To put it in perspective, last week's planet was bzip2 compressed at 7.4GB, unzipping to 116GB, and occupying 113GB in a PostGIS database. The process of importing the data is very serious: even with a large Amazon instance which lets me allocate five gigabytes of RAM for the importer, the initial load takes over 29 hours.
Graphic cards contain a lot of very fast RAM, typically between 64 and 512 MB. With Linux, it's possible to use it as swap space, or even as RAM disk.
– un peu plus de mémoire disponible ... Firefox MemMoins permet de convertir la mémoire RAM utilisée par Firefox en une mémoire paginée accessible sur le disque. ..
Using Maven sometimes becomes a pain for a large project.
Pour les petits projets aussi remarque.

Déboguer Firefox : comment limiter l’utilisation de mémoire RAM?
il rassemble tous les ports, disques durs, ram, connecteurs, sockets…etc qu’on peut trouver dans nos ordinateurs… Ainsi vous ne serez plus jamais pris au dépourvu devant un connecteur que vous n’avez jamais vu. A conserver accroché au mur pour tous les fanas de hardware, en guise de memento.
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...
Post ThinkFree lança pacote office para netbooks Postado por Das Übergeek - ubergeek@geek.com.br em 18/06/2009 16:00 Blog: Notícias adicionar comentário Comment Pacote combina editor de textos, planilha e software para apresentações compatíveis com o Microsoft Office com armazenamento de documentos online Por Antonio Blanc A ThinkFree lançou nesta semana uma versão de seu pacote office, o ThinkFree Office, especialmente adaptada para netbooks. O conjunto de aplicativos é composto por editor de textos, planilha de cálculo e software para apresentações, todos compatíveis com o Microsoft Office, e 1 GB de espaço para armazenamento online de seus documentos, que poderão ser acessados a partir de qualquer computador conectado à internet. Segundo a empresa, seus aplicativos são carregados rapidamente, ocupam pouco espaço em disco, pouca RAM e são otimizados para telas de baixa resolução, características desejáveis entre os usuários de netbooks. O pacote também é multi-plataforma: há versões para Windows (XP ou Vista), Linux (kernel 2.6.17 ou mais recente) e Macs (OS X 10.5), e também para sistemas baseados em processadores ARMv6 ou ARMv7. O ThinkFree Office também tem versões para MIDs (Mobile Internet Devices) e smartphones baseados no sistema operacional Android, do Google. A versão otimizada para netbooks custa US$ 39.95. Uma cópia de demonstração, completamente funcional por sete dias, pode ser baixada gratuitamente no site do fabricante. www.geek.com.br

APC (Alternative PHP Cache) is a PHP opcode cache. It stores PHP pages in RAM and reduces hard disk activity. This makes a real difference to the performance in Moodle, and you should be able to achieve a 50% increase in system capacity and your CPU will be 50% less busy. This guide is for installation of APC on a Windows server. The instructions have been tested on a Windows 2003 server, and they should also be applicable if you are using Windows XP as a test server.

Out of the box, Zimbra is tuned for a fairly beefy machine. Zimbra will easily consume 1.5GB of ram with default settings. Some of these changes mean turning off a few Zimbra features and there are quite a few ways to do this, so you will need to evaluate memory usage given your own situation. If you simply can't live without *all* the Zimbra features or intend to support a larger (> 15) number of users, my only suggestion is to get more ram ;). But if you are willing to make some compromises, please read on. The changes below are ones that I found to be a reasonable compromise. With a few easy changes, you can bring the memory consumption way down, so that it will hum along just fine on a server with ~512MB of ram. Of course this reduces the amount of users that your server can support, but I've found that for a small installation of around 15 users, these settings will work just fine and give you the same performance as the out-of-the-box config with gobs of RAM. The server I have been testing with has 560MB of ram, and after tuning consumes all the ram and only about 80MB of swap on average. You will find that if you don't make changes similar to the ones suggested below with ~512MB of ram, your Zimbra install will slowly creep up its consumption of swap and your Zimbra install will start to crawl. Also, > 512MB seems to be about the minimum amount of ram to get a useful/zippy server
