Detailed Description

A simple class to make throughput and latency analysis.

Keep the relevant information to perform throughput and latency analysis, including:

  1. Minimum, Average and Maximum latency
  2. Jitter for the latency
  3. Linear regression for throughput
  4. Accumulate results from several samples to obtain aggregated results, across several threads or experiments.

Todo:
The idea behind this class was to use linear regression to determine if the throughput was linear or exhibited jitter. Unfortunately it never worked quite right, so only average throughput is computed.
