The “Parse XML” time refers to the time required to extract the data values from
the XML, and the “Setup Mesh” time refers to the time required to convert the
extracted data into the required format for OpenGL rendering. “Total Time”
includes all these factors and other elements of timing (e.g. to change activity from
download to rendering), and all times are measured in milli-seconds. Both the
