Bottleneck is a step within a series of steps that takes the longest time to complete.
Time required to perform a task consisting of several steps may be delayed by the bottleneck step.
Process time cannot be shortened without speeding up the bottleneck.

To speed up performance of a system:
Use profiling tools to measure each section’s time taken to complete to determine the bottleneck steps
Improve upon the bottleneck steps
