ANTS Memory Profiler 5 is our new, completely rewritten, memory profiler. It offers the following features and benefits:

• Unparalleled performance
• Ability to take and analyse an arbitrarily large number of memory snapshots
• Support for snapshots up to 2GB (32-bit operating systems), and 4GB (64-bit operating systems)
• Arbitrary snapshot comparisons
• Summary information for profiling session, individual snapshots, and snapshot comparisons
• Large object heap fragmentation statistics
• Extremely powerful filtering options to narrow down to the objects you really need to know about
• A unique class graph view which allows you to quickly see where instances of a given class are being referenced
• A unique object retention graph, which quickly allows you to see shortest reference paths to all GC roots, which will need to be broken to fix memory leaks
• Ability to profile .NET executables, ASP.NET applications and web services in IIS and web development server, services, COM+ applications, and XBAP applications.

Before version 5.0, ANTS Memory Profiler was part of the ANTS Profiler product.
