      1. What would you like to communicate to the user about this feature?
      2. Would you like the user to see examples of the syntax and/or executable code and its output?
      3. Which versions of the driver/connector does this apply to?

      After the changes in PYTHON-4350, the GridFsMultiFileDownload benchmark has high variance. For example the most recent build dropped by 15%: https://spruce.mongodb.com/task/mongo_python_driver_perf_tests_perf_6.0_standalone_e40ff3516821ce79252bef60fce41bf3d93ae110_24_04_11_01_19_51/trend-charts?execution=0&sortBy=STATUS&sortDir=ASC

      This could also be related to HELP-58235.

      For now we should increase the benchmark runtime from 60 seconds back to 3-5 minutes.
