“…To quantify the server's behaviour, a variety of metrics are collected. To monitor the CPU, disk and network utilizations of the server, the collectl [35] tool is used, which we confirmed incurred a negligible CPU overhead of around 1%. Low-level hardware monitoring data were collected using the Performance Counter Monitor (PCM) [36] tool (specific to Intel architectures).…”

The advent of multi-core technology motivates new studies to understand how efficiently Web servers utilize such hardware. This paper presents a detailed performance study of a Web server application deployed on a modern eight-core server. Our study shows that default Web server configurations result in poor scalability with increasing core counts. We study two different types of workloads, namely, a workload with intense TCP/IP related OS activity and the SPECweb2009 Support workload with more application-level processing. We observe that the scaling behaviour is markedly different for these workloads, mainly because of the difference in the performance of static and dynamic requests. While static requests perform poorly when moving from using one socket to both sockets in the system, the converse is true for dynamic requests. We show that, contrary to what was suggested by previous work, Web server scalability improvement policies need to be adapted based on the type of workload experienced by the server. The results of our experiments reveal that with workload-specific Web server configuration strategies, a multi-core server can be utilized up to 80% while still serving requests without significant queuing delays; utilizations beyond 90% are also possible, while still serving requests with 'acceptable' response times.

“…Embora seja impossível representar sua extensão e dimensão atuais, dois modelos da Teerã contemporânea podem indicar as mudanças e as forças motrizes por detrás delas. Assim, a tentativa de Seger (1975Seger ( , 1978 de representar Teerã como uma cidade bipolarizada, com um pequeno centro tradicional e um amplo tecido urbano moderno em constante expansão, com todas as suas diferenciações sociais e econômicas, é uma forma de reconciliação entre ideal e realidade. Uma outra tentativa de combinar o antigo e o novo, a tradição e a modernidade, é uma abordagem que hesito em chamar de 'modelo'.…”

Uma série de modelos de forma urbana são examinados numa perspectiva transcultural. Sem pretender ser abrangente e baseado, em grande parte, nas descobertas de pesquisadores de língua alemã, argumenta-se que existem vários modelos de forma urbana que servem como representações descritivas úteis de condições culturais e históricas específicas. Todavia, tais modelos são, na sua maioria, aplicáveis ao tecido urbano histórico de um mundo pré-globalizado e têm valor limitado fora dos núcleos históricos das vilas e cidades tradicionais.
