Performance Results

[troygrosfield]

This isn't as much of an issue as it is simply to be informative about performance results on form rendering for this repo.

The script goes through and times the rendering of 1000 forms.

The Script

from datetime import datetime

from bootstrap3.templatetags.bootstrap3 import bootstrap_form
from django import forms


class SomeTestForm(forms.Form):
    field_1 = forms.CharField(max_length=20)
    field_2 = forms.CharField(max_length=20)
    field_3 = forms.CharField(max_length=20)
    field_4 = forms.CharField(max_length=20)
    field_5 = forms.CharField(max_length=20)


def create_form():
    initial = {
        'field_1': 'Some random string 1.',
        'field_2': 'Some random string 2.',
        'field_3': 'Some random string 3.',
        'field_4': 'Some random string 4.',
        'field_5': 'Some random string 5.'
    }
    return SomeTestForm(initial=initial)

# Test rendering 1000 forms
forms = [create_form() for f in range(1000)]

# Test django forms
start_time_django_rendering = datetime.utcnow()

for form in forms:
    form.as_table()

end_time_django_rendering = datetime.utcnow()
total_django_rendering_time = (end_time_django_rendering - start_time_django_rendering)

print('Total django rendering time: {0}'.format(total_django_rendering_time))

# Test this repo
start_time_bootstrap = datetime.utcnow()

for form in forms:
    bootstrap_form(form)

end_time_bootstrap = datetime.utcnow()
total_bootstrap_time = end_time_bootstrap - start_time_bootstrap

print('Total bootstrap rendering time: {0}'.format(total_bootstrap_time))

I ran the same tests against the django-bootstrap-form repo and they didn't do as well:

• Performance Issues, ~6x longer to render than regular django forms tzangms/django-bootstrap-form#62

@dyve, feel free to close this once you've seen it. This repo does a pretty good job with rendering performance!
