• The operating system
• The hardware
• The load generator

Don’t let all of this overwhelm you. To minimize the complexity of it all, we developers should first focus on the performance of the part we’re responsible for—the code. This is the Code First approach. A healthy percentage of performance defects are write-once-run-anywhere issues that will ...
