Using Graphics Card Memory as Swap - Gentoo Linux Wiki
by ghis
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.

Chrome and Firefox 3.5 Memory Usage
by night.kame
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...

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.

Installing APC in Windows - MoodleDocs
by holyver
(via)
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.

Zimbra on a VPS: Tuning - Misc - Rob Thompson
by camel
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

SIVIT - Les Serveurs Virtuels
by mozkart
Point d'orgue de la gamme VDS, ce serveur vous permet de disposer d'une puissance considérable, par une réservation très importante de Cpu et Ram sur le serveur hôte.
Doté d'un espace disque très confortable, ce serveur vous permettra d'héberger de nombreux sites, ou bien de faire tourner des applications gourmandes, dans des conditions excellentes.
Bien meilleur qu'un serveur dédié d'entrée de gamme, il est la solution à retenir lorsque vous recherchez des performances importantes pour un budget modéré.

How To Set Up A Load-Balanced MySQL Cluster With MySQL 5.1 | HowtoForge - Linux Howtos and Tutorials
by camel
This tutorial is based on Falko Timme's tutorial for MySQL Cluster 5.0. It shows how to configure a MySQL 5.1 cluster with five nodes: 1 x management, 2 x storage nodes and 2 x balancer nodes. This cluster is load-balanced by an Ultra Monkey package which provides heartbeat (for checking if the other node is still alive) and ldirectord (to split up the requests to the nodes of the MySQL cluster).
In this document I use Debian Etch 4.0 for all nodes. Therefore the setup might differ a bit for other distributions. The two data nodes were x64 to use all of the 8GB RAM. Servers were compiled from source so you should be able to make it running on any platform. The MySQL version I use in this setup is 5.1.24-rc. It's a release candidate, but I wanted to use 5.1 to take advantage of Memory-Disk Based tables.
Beginning with MySQL 5.1.6, it is possible to store the non-indexed columns of NDB tables on disk, rather than in RAM as with previous versions of MySQL Cluster.
