# This script demonstrates a performance regression introduced in https://github.com/rails/rails/pull/34405
# That PR patched ActiveSupport::SafeBuffer methods gsub, gsub!, sub and sub! to set backreferences, but
# in doing so incurred a significant penalty.
# 
# This script creates a random string with texts at random locations which are swapped with gsub. The string
# is random but seeded the same each run, so the same length produces the same string.
