Hi

Is it possible to compare methods time execution...

I know the possiblity to use Time millisecondsToRun: aBlock but it's not really useful... I've seen a profiler but not really sure...

My aim is just to compare for instance the access to an existing dictionary, or creating it with several methods...

I use the "TimeProfileBrowser":

TimeProfileBrowser spyOn: ["your code goes here"]

The code in the block should take at least 1 second to get a reasonable number of samples. If you need to you can always do something like:

TimeProfileBrowser spyOn: [100 timesRepeat: ["your code goes here"]]

Keep in mind that spyOn: does its work by sampling the stack at fixed intervals...have a look at the class docs for MessageTally for more details and alternatives.
