# Sample: what is the effect of doc size on indexing time?
#
# There are two parts in this test:
# - PopulateShort adds 2N documents of length  L
# - PopulateLong  adds  N documents of length 2L
# Which one would be faster?
# The comparison is done twice.

# multi val params are iterated by NewRound's, added to reports, start with column name.
