+Measured on Windows 10 22H2 with an Intel Core i7-8750H and 8 GB of RAM,
+opening a short Markdown file. Each figure is the median of three runs.
+Memory, threads and handles are summed over all of the app's processes,
+15 seconds after the document opened; idle CPU is averaged over the next
+10 seconds.
