Performance Management with Free and Bundled Tools by Adrian Cockcroft and Mario Jauvin


It is often difficult to separate information how to design systems with good performance (architecture, performance patterns, language structures, etc.) from information how to tune and deploy systems, quite often both sides are considered. Although more tuning- and product - oriented links are placed here, a lot of related information can be found in the Performance section. See also Bottlenecks.
