WARNING: The results of this benchmark are useless to compare the
|
||
|
|
performance of template engines and should not be taken seriously in any
|
||
|
|
way. It's testing the performance of simple loops and has no real-world
|
||
|
|
usefulnes. It only used to check if changes on the Jinja code affect
|
||
|
|
performance in a good or bad way and how it roughly compares to others.
