Comment (by Johannes Maron):
I used the following script to benchmark:
{{{
import timeit
from django.forms.widgets import Script, Stylesheet
# Setup: create instances to compare
setup = """
import os
os.environ.setdefault("DJANGO_SETTINGS_MODULE",
"tests.staticfiles_tests.settings")
import django
django.setup()
from django.forms.widgets import Script, Stylesheet
s1 = Script("vendor/jquery.js")
s2 = Script("vendor/jquery.js")
s3 = Script("vendor/other.js")
ss1 = Stylesheet("vendor/style.css")
ss2 = Stylesheet("vendor/style.css")
ss3 = Stylesheet("vendor/other.css")
"""
benchmarks = {
"Script equal (same path)": "s1 == s2",
"Script not equal (diff path)": "s1 == s3",
"Script equal to str": "s1 == 'vendor/jquery.js'",
"Script not equal to str": "s1 == 'vendor/other.js'",
"Stylesheet equal (same path)": "ss1 == ss2",
"Stylesheet not equal (diff path)": "ss1 == ss3",
"Stylesheet equal to str": "ss1 == 'vendor/style.css'",
"Stylesheet not equal to str": "ss1 == 'vendor/other.css'",
}
N = 1_000_000
print(f"{'Benchmark':<40} {'Total (s)':>10} {'Per call (ns)':>14}")
print("-" * 66)
for label, stmt in benchmarks.items():
t = timeit.timeit(stmt, setup=setup, number=N)
print(f"{label:<40} {t:>10.4f} {t / N * 1e9:>13.1f}ns")
}}}
