Analyzing and remediating latency sensitive applications part 1
Examples of latency sensitive applications In the previous post http://www.shunra.com/shunrablog/index.php/2009/08/14/data-center-relocation-questions-and-answers-part-1/ I shared some of the questions that clients typically ask me during the performance analysis service in a data center relocation project.
