Apache Performance Tuning

Question récurrente pour un développeur suffisamment proche du système pour si intéresser:
quel est le cout processeur & ram de mon langage de programmation ?

Un élément de réponse avec ce graphique comparatif:

Matériel

• processeur: VIA C7 2 GHz
• disque dur: 160 Go SATA
• ram: 1024 Mo DDR2

#dbench 1
Throughput 156.652 MB/sec 1 procs

Le taux de tranfert d’un disque dur sur une dedibox est d’environ 150Mo/sec
