Dear Friends and Colleagues,
We are happy to announce Memory Profiler, a new profiler for Pharo. This profiler gives a nice output that indicates the memory consumption along the method call graph. Consider the following piece of code:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
(MSP profile: [
Object browse
] onPackagesMatching: 'Nautilus*' ) inspect
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Consider that MSP uses instrumentation, therefore long execution may take really long. The code above takes about 19 seconds on my iMac.
It opens a visualization that indicates some interesting fact about memory consumption. For example, the expression ���Object browse��� consumes 14 851 kb with instances of the class Point. More than 1M of points are created.
Here is the blueprint obtained:
A description of the visualization is available here:
You need to load Spy from the Configuration Browser. Else the following incantation should work:
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Gofer it
smalltalkhubUser: 'ObjectProfile' project: 'S2py';
configurationOf: 'Spy';
loadDevelopment.
-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=-=
Cheers,
Alejandro & Alexandre
