<p>All HTML pages will have profiling information appended to them.
The data is isolated to that single request, and does not include
data from previous requests.</p>
<p>This uses the <tt class="docutils literal"><span class="pre">hotshot</span></tt> module, which affects performance of the
application. It also runs in a single-threaded mode, so it is
only usable in development environments.</p>

<dd><p>Wrap the application in a component that will profile each

Default: stderr.</dd>
<dt>display_limit:</dt>
<dd>Only show the top N items, default: 20.</dd>
<dt>sort_stats:</dt>
<dd>A list of string-attributes to sort on. Default
<tt class="docutils literal"><span class="pre">('time',</span> <span class="pre">'calls')</span></tt>.</dd>
<dt>strip_dirs:</dt>
<dd>Strip directories/module names from files? Default True.</dd>
<dt>add_info:</dt>
<dd>If given, this info will be added to the report (for your
own tracking). Default: none.</dd>
<dt>log_filename:</dt>
