# This profiler run simulates Shopify.

# We are looking in the tests directory for liquid files and render them within the designated layout file.
|
|
# We will also export a substantial database to liquid which the templates can render values of.
|
|
# All this is to make the benchmark as non syntetic as possible. All templates and tests are lifted from
|
|
# direct real-world usage and the profiler measures code that looks very similar to the way it looks in
|
|
# Shopify which is likely the biggest user of liquid in the world which something to the tune of several
|
|
# million Template#render calls a day.
