Who should attend: Novice and advanced UNIX system and network administrators, UNIX developers concerned about network performance impacts. A basic understanding of the UNIX system facilities and network environments is assumed.

We will explore procedures and techniques for tuning systems, networks and application code. Starting from the single system view, we will examine how the virtual memory system, the I/O system, and filesystem can be measured and optimized. We'll extend the single host view to include Network File System tuning and performance strategies. Detailed treatment of networking performance problems, including network design and media choices will lead to examples of network capacity planning. Application issues, such as system call optimization, memory usage and monitoring, code profiling, real-time programming, and techniques for controlling response time will be addressed. Many examples will be given, along with guidelines for capacity planning and customized monitoring based of your workloads and traffic patterns. Question and analysis periods for particular situations will be provided.
