Para simular alguns cen\u00e1rios de performance em laborat\u00f3rio, vou fazer uso do utilit\u00e1rio de Sistema Operacional Linux chamado “stress”, que reproduz o consumo de recursos como CPU, mem\u00f3ria, I\/O, etc. O uso dele em si abordarei em outros artigos, e neste mostrarei apenas a sua instala\u00e7\u00e3o.<\/p>\n\n\n\n
