~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
This module provides a simple WSGI profiler middleware for finding
|
|
bottlenecks in web application. It uses the :mod:`profile` or
|
|
:mod:`cProfile` module to do the profiling and writes the stats to the
|
|
stream provided (defaults to stderr).
|
|
|
|
Example usage::
|
|
|
|
from werkzeug.contrib.profiler import ProfilerMiddleware
|
|
app = ProfilerMiddleware(app)
