Es decir haz un benchmark de 1500 usuarios concurrentes a la siguiente URL… se que no es totalmente un calculo concluyente, pero ha sido divertido,tambien no tengo el apache configurado para maximo desempe\u00f1o, ni mucho menos mysql para conexiones persistentes es decir es una maquina tal cual la uso para probar, sin ninguna optimizacion – excepto del kernel, y ni asi tengo incluido el de matar tareas de acuerdo a uso de memoria, comprobado queda que requiere de mas carga el vb que el phbb ;D en la DB, bueno tambien tengo poca memoria en mi maquina de casa, seria interesante probarlo en uno de nuestros U450 de 4GB de Ram…<\/p>\n
