Monitoring package. Instrument the code like this:
use Monitor; Monitor::MARK("Description of event"); Monitor::MARK("Another event");
or, to monitor all the calls to a module
use Monitor; Monitor::MonitorMethod('TWiki::Users');
or a function
use Monitor; Monitor::MonitorMethod('TWiki::Users', 'getCanonicalUserID');
Then set the environment variable TWIKI_MONITOR to a perl true value, and run the script from the command line e.g: $ cd bin $ ./view -topic Myweb/MyTestTopic
The results will be printed to STDERR at the end of the run. Two times are shown, a time relative to the last MARK and a time relative to the first MARK (which is always set the first time this package is used). The final column is total memory.
NOTE: it uses /proc - so its linux specific...
