Stores some values related to performance.
These are usually set by Launch.py or AppServer.py.
To get profiling going, locate the "runProfile = False" line towards the top
of WebKit/Launch.py and change the "False" to "True", or start the Launch.py
script with the --run-profile option. When the app server shuts down it
will write a profiling report "profile.pstats" in the directory containing
the Launch.py script which can be quickly examined from the command line:
$ cd Webware
$ bin/printprof.py WebKit/profile.pstats
Using the RunSnakeRun (http://www.vrplumber.com/programming/runsnakerun/)
GUI utility you can even visualize the data in the profile.pstats file.
You might also wish to dump the profiling stats on demand (as in, by
clicking or reloading a URL for that purpose). Read further for details.
The variables in this module are:
An instance of Python's profile.Profiler, but only if Launch.py is
started with profiling enabled. Otherwise, this is None.
You could access this from a servlet in order to dump stats:
from WebKit.Profiler import dumpStats
With some work, you could dump them directly to the page in a
The earliest recordable time() when the app server program was
The time() and duration from startTime for when the app server
was ready to start accepting requests. A smaller readyDuration
makes application reloading faster which is useful when
developing with AutoReload on.
