Eliot Miranda uploaded a new version of System to project The Trunk: http://source.squeak.org/trunk/System-eem.491.mcz ==================== Summary ==================== Name: System-eem.491 Author: eem Time: 16 July 2012, 5:15:37.638 pm UUID: 36631b36-5c57-4173-af46-59e4697db35b Ancestors: System-eem.490 Make MessageTally able to profile across a snapshot. See MessageTally's class comment for an example. =============== Diff against System-eem.490 =============== Item was changed: Magnitude subclass: #MessageTally + instanceVariableNames: 'class method process tally receivers senders time gcStats maxClassNameSize maxClassPlusSelectorSize maxTabs reportOtherProcesses time0 startTime endTime preHibernationCopy' - instanceVariableNames: 'class method process tally receivers senders time gcStats maxClassNameSize maxClassPlusSelectorSize maxTabs reportOtherProcesses' classVariableNames: 'DefaultPollPeriod ShowProcesses Timer' poolDictionaries: '' category: 'System-Tools'! + !MessageTally commentStamp: 'eem 7/16/2012 17:10' prior: 0! - !MessageTally commentStamp: 'StephaneDucasse 9/27/2009 10:42' prior: 0! My instances observe and report the amount of time spent in methods. NOTE: a higher-level user interface (combining the MessageTally result tree with a method browser) is available from TimeProfileBrowser. Note that TimeProfileBrowser was not fancy with the different setting possibilities. TimeProfileBrowser spyOn: [20 timesRepeat: [Transcript show: 100 factorial printString]] Strategies ----------- MessageTally provides two different strategies available for profiling: * spyOn: and friends use a high-priority Process to interrupt the block or process being spied on at periodic intervals. The interrupted call stack is then examined for caller information. See below for an example showing different settings * tallySends: and friends use the interpreter simulator to run the block, recording every method call. The two give you different results: * spyOn: gives you a view of where the time is being spent in your program, at least on a rough statistical level (assuming you've run the block for long enough and have a high enough poll rate). If you're trying to optimize your code, start here and optimize the methods where most of the time is being spent first. * tallySends: gives you accurate counts of how many times methods get called, and by exactly which route. If you're debugging, or trying to figure out if a given method is getting called too many times, this is your tool. Q: How do you interpret MessageTally>>tallySends A: The methods #tallySends and #spyOn: measure two very different quantities, but broken down in the same who-called-who format. #spyOn: is approximate, but more indicative of real time spent, whereas #tallySends is exact and a precise record of how many times each method got executed. Examples ---------- Here you can see all the processes computation time [1000 timesRepeat: [3.14159 printString. Processor yield]] fork. [1000 timesRepeat: [30 factorial. Processor yield]] fork. [1000 timesRepeat: [30 factorial. Processor yield]] fork.
