The concurrency information desired is the proportion of time there are 0, 1, 2, etc. web events resident in the system under test. These proportions are not always available from target system measurements but, as will be shown, can be approximated with data produced by the load generator, or estimated using queueing models. The data analysis and queueing model tools that support the ideas presented were developed by this author and contained in two of his GitHub repositories, web-generator-toolkit2 and QueState, as free open source downloads.
