.NET Framework Allocation Complexity Graph

  • Artikel

A quick graphical view of how the framework measures up.

 

This graph shows the number of methods of any given allocation complexity on a logarithmic scale.  This allocation complexity is discussed in more detail in performance quiz #12 and this summary of my CMG talk on performance signatures.

Remember this is just a rough number, imperfect in many ways, it's only interesting to give you a general feeling about where particular methods are in the food-chain.  It's useful as a planning tool but not a replacement for actual measurement.  And despite the fact that I think this metric has several flaws, which I'll be discussing them in coming postings, even this feeble metric is actually useful -- an amazing result in an of itself.

    I want to measure our library this way. Is there any tool for this? Thanks.

    The thing that I used to make the data isn't shipped in any way.  I might be able to do something about that but I can't promise anything just yet. Ultimately I think it would be cool if you could compute any cost you like of your own with a little library and some custom code.

    To rephrase this post (or rant) in a nutshell: Measuring performance is not as simple as people think
