Performance and Availability Characterization for Linux Servers
The performance of Linux servers running in mission-critical environments such as telecommunication networks is a critical attribute. Its importance is growing due to incorporated high availability approaches, especially for servers requiring five and six nines availability. With the growing number of requirements that Linux servers must meet in areas of performance, security, reliability, and serviceability, it is becoming a difficult task to optimize all the architecture layers and parameters to meet the user needs. Other Linux servers, those not operating in a mission-critical environment, also require different approaches to optimization to meet specific constraints of their operating environment, such as traffic type and intensity, types of calculations, memory, and CPU and IO use.
