To perform a data transfer rate analysis, press the "Analyze" button.
To obtain a better assessment of your average bitrate, select a larger data transfer size. If you select a smaller size, the analysis will complete sooner, but the result will reflect a more instantaneous data transfer rate.
If you have a very low data transfer rate, select a smaller data transfer size. Otherwise, you may have to wait a while for the analysis to complete. If you are not sure, start with the default data transfer size of 512 KB.
