In the current economic downturn, performance tuning takes on a new importance. It allows system administrators to make the best use of existing systems and minimize the purchase of new equipment. Well-tuned systems save money and time that would otherwise be wasted dealing with slowdowns and errors. Performance tuning always involves compromises; unless system administrators know what the compromises are, they can't make intelligent decisions.Tuning is an essential skill for system administrators who face the problem of adapting the speed of a computer system to the speed requirements imposed by the real world. It requires a detailed understanding of the inner workings of the computer and its architecture. System Performance Tuning covers two distinct areas: performance tuning, or the art of increasing performance for a specific application, and capacity planning, or deciding what hardware best fulfills a given role. Underpinning both subjects is the science of computer architecture. This book focuses on the operating system, the underlying hardware, and their interactions. Topics covered include:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eReal and perceived performance problems, introducing capacity planning and performance monitoring (highlighting their strengths and weaknesses). \u003c\/li\u003e\n\u003cli\u003eAn integrated description of all the major tools at a system administrator's disposal for tracking down system performance problems. \u003c\/li\u003e\n\u003cli\u003eBackground on modern memory handling techniques, including the memory-caching filesystem implementations in Solaris and AIX.
