What is the most efficient way to present and report performance improvements (e.g. percentages, raw data, graphics)?

Is it better to describe improvements using percentages or simply differences in numbers? For example, if you increased the performance of a critical SQL ETL query from 4000 ms to 312 ms, how would you present it as an “Achievement” in the performance overview?
