# Note: CSV parses are NOT DIRECTLY COMPARABLE.
#  - data.table does not parse dates, it just gives strings.
#  - data.table is only fast when OpenMP is supported, i.e. not on MacOS.
#  - vroom takes advantage of altrep, which defers some parsing.
#  - arrow takes advantage of hardware extensions if available.
#  - results will be different if you specify the types of the columns.
