> is a memory optimization App for Mac developers, an essential part
> of any Mac OS X developer's toolbox: a tool that makes it easy for
> Cocoa and Unix developers to find and fix memory leaks, excessive
> allocation operations, "zombies", prematurely deallocated objects,
> and other performance issues. The end product is faster and more
> robust applications.
>
> Rather than searching through the thousands of objects and
> allocation events in a program, you can use OmniObjectMeter to
> quickly seek and destroy problematic code, and spend your time
> fixing problems rather than looking for them:
>
> OmniObjectMeter shows allocated blocks, allocation events for each
> block, and the stack trace responsible for each allocation event. In
> the case of Cocoa or CoreFoundation objects, OmniObjectMeter also
> allows you to easily match retain events with their corresponding
> release events ? once you have done this for a leaked object, there
> will be some number of extra retain events left unmatched which are
> causing the leak.
>
> If a program accidentally keeps a pointer to a deallocated Cocoa or
> CoreFoundation object and later attempts to access that object, it's
> likely to crash. OmniObjectMeter integrates nicely with the built-in
> Cocoa support for detecting these so-called 'zombie' objects: By
> flipping a switch in OmniObjectMeter you can detect the first
> message to a zombie object and then look at the allocation event
> history for that object to determine why the object was prematurely
> deallocated.
>
> OmniObjectMeter is also useful for optimizing memory usage. Since
> OmniObjectMeter shows you memory allocated split up by category, you
> can see how much memory each category is using. OmniObjectMeter can
> display the memory allocation events (or any other event type) for a
> category in a hierarchical tree formed from the stack trace
> responsible for each event. This allows you to see what portion of
> your code is responsible for what portion of the category's
> allocation usage, which makes it easy to identify and fix problem
> spots.
>
> CPU utilization can be improved by reducing the number of needless
> allocation events. If the allocation and deallocation events for an
> object happen near each other in time, often the object really
> shouldn't have been deallocated anyway. Since OmniObjectMeter can
> easily group objects together to look at them on a category-by-
> category basis, you can use it to quickly find places where you're
> using lots of short-lived objects.
>
> OmniObjectMeter integrates with Apple's Project Builder IDE: any
> place a stack frame is displayed, a source icon will appear next to
> the frame if appropriate debugging symbols are available in the
> application. Clicking on the icon will open the source file in
> Project Builder and select the correct line.
>
> Note
>  To enable opening source code files in Project Builder from within
> OmniObjectMeter, drag the OOMProjectBuilder.pbplugin into either of
> the following folders:
>  /developer/projectBuilder Extra/Plug-ins
>  ~/developer/projectBuilder Extra/Plug-ins
