Rediscover the Lost Art of Memory Optimization in Your Managed Code

摘要

Memory is the one resource all programs require, yet wise memory usage is becoming a lost art. Managed applications written for the Microsoft~(~R) .NET Framework rely on the garbage collector to allocate and clean up memory. For many applications, the three, to five percent of CPU time spent performing garbage collection (GC) is a fair trade-off for not having to worry about memory management. But for applications in which CPU time and memory are precious resources, minimizing the time spent garbage collecting can greatly improve application performance and robustness. If an application can more effectively use available memory, then it stands to reason that the garbage collector would run less often and for shorter periods of time. So rather than looking at what the garbage collector is or is not doing in your applications, take a look at memory usage directly.
