MCG 3.3 with treemaps

We’ve just released MCG version 3.3 on the Mac App Store, the major change being the addition of treemaps. Both Flat and Outline modes get their own fast treemap visualizations, including heat map color coding and zoom navigation. This release also includes the start of a help book, including MCG overview help and extensive treemap help. And we've also included a few minor keyboard navigation and UI tweaks.

  • Profile, analyse and tune your code.
  • Parses any callgrind file generated by many languages including Ruby, Python, C++, PHP, Perl, C++.
  • Shows drillable excution call tree and caller/callee, with generic cost support such as timing and memory.
  • Structual code graphs for analysing code structure.

Language support

MCG parses most callgrind files but has specific syntax highlighting and markup for those working with PHP (Xdebug), Ruby or Python. We provide highlighting for includes, language and application functions. With icon markup for functions, class method and instance methods you'll be able to find the function you're looking for in no time.

Or just use our built in function search to jump directly to the function you're interested in.

Hierarchy display

If the callgrind file is in a specific format, we go one further and give you a full call hierarchy. Currently supported in Xdebug files, MCG can help you nail the performance issue you have with one of the world's favourite web scripting languages.

Graphs, graphs and treemaps

MCG ships with a number of structural overview graphs and treemap to help you visualise what your application is doing. Find out if you're spending all your time in language or application functions, what classes are taking the brunt of the work and specifically which functions in those classes.

MCG helps you target the functions you need to be high performing by identifying code for performance regression testing.

What our customers say

"Great app.

— Modi34

"A client came to me with CPU spike causing traffic delays. The sysadmin hooked up xdebug and profiled some stuff during these spikes, but they couldn't make heads or tails of it. Your software allowed me to bill a couple hours I wouldn't have -- so the software paid for itself as soon as it downloaded.
