Assessing Performance of Network Systems
Introduction As development of software services moves from a local development environment environment to a staging or production environment, a common concern that arises is to know the limits of what the system can handle in terms of performance. Knowledge of what your system can handle is useful for several reasons: Performance numbers are often…

Language and Performance: Java and D
Introduction In the previous article, Perspectives on Software Performance, it was discussed how the computational performance and efficient use of RAM can be used to greatly lower the costs associated with solving a given business problem. In this article, the impact of the choice of technology will be further elaborated. This analysis will focus on…

Perspectives on Software Performance
Early decisions in system design can have long-term consequences which are hard to change later on. The changes to the system made in response to growing load are rarely given careful consideration, as they are frequently implemented during an emergency so severe that it can no longer be ignored. The ultimate result is a system that becomes increasingly complex, hard to work with, and costly in both hardware and engineering-hours needed to make changes.
