Interest about performance in.NET have increased recently with the advent of.NET Standard and new platforms opened to.NET applications..NET. Possible Duplicate: What Are Some Good.NET Profilers? I am on the lookout for good.NET CLR memory profiling tools. My key requirement is that it will play well. Memory profiler and unit-testing framework for.NET applications. Redgate makes ingeniously simple tools used by over 600,000 SQL Server,.NET, and Oracle professionals worldwide. .NET Memory Profiler 5.5.NET Memory Profiler is the flagship product of SciTech Software. It is a powerful tool for finding memory leaks and optimizing.

Failure to launch: Code, Upload, and Explode by Microsoft MVP Jeremiah Peschka Before you load your valuable ASP.NET application into a rocket and aim for the cloud, let's do a sanity check. How do you handle bandwidth shortages that never let your app reach orbit? What happens if you need more speed to haul all these users up? If your uptime flames out, how can you easily plan for splashdown?
Moving an ASP.NET application to the cloud may not be as difficult as putting someone on the moon, but there are a lot of places where something can go wrong. In this session you'll learn how to handle the limitations of a purely virtual environment, measure performance and identify bottlenecks, and deal with the changing availability of resources Datasheet.

Find memory leaks and inefficient memory use in.NET Framework code by using the Visual Studio managed memory analyzer. The minimum.NET Framework version of the target code is.NET Framework 4.5. The memory analysis tool analyzes information in dump files with heap data that a copy of the objects in an app's memory. You can collect dump (.dmp) files from the Visual Studio IDE or by using other system tools. • You can analyze a single snapshot to understand the relative impact of the object types on memory use, and to find code in your app that uses memory inefficiently. • You can also compare ( diff) two snapshots of an app to find areas in your code that cause the memory use to increase over time. For a walkthrough of the managed memory analyzer, see on the Visual Studio ALM + Team Foundation Server blog.
The.NET Framework is a garbage-collected runtime, so that in most apps, memory use is not a problem. But in long-running applications like web services and applications, and in devices that have a limited amount of memory, the accumulation of objects in memory can impact the performance of the app and the device that it runs on. Excessive memory use can starve the application and the machine of resources if the garbage collector is running too often, or if the operating system is forced to move memory between RAM and disk. In the worst case, an app can crash with an 'Out of memory' exception. The.NET managed heap is a region of virtual memory where reference objects created by an app are stored. The lifetime of objects are managed by the garbage collector (GC). The garbage collector uses references to keep track of objects that occupy blocks of memory.
A reference is created when an object is created and assigned to a variable. A single object can have multiple references. For example, additional references to an object can be created by adding the object to a class, collection, or other data structure, or by assigning the object to a second variable.
A less obvious way of creating a reference is by one object adding a handler to another object's event. In this case, the second object holds the reference to the first object until the handler is explicitly removed or the second object is destroyed. For each application, the GC maintains a tree of references that tracks the objects referenced by the application. The reference tree has a set of roots, which includes global and static objects, as well as associated thread stacks and dynamically instantiated objects.
An object is rooted if the object has at least one parent object that holds a reference to it. The GC can reclaim the memory of an object only when no other object or variable in the application has a reference to it. Note Most tools can collect dump information with or without complete heap memory data. The Visual Studio memory analyzer requires full heap information. To collect a dump from Visual Studio • You can create a dump file for a process that was started from a Visual Studio project, or you can attach the debugger to a running process.
• Stop execution. The debugger stops when you choose Break All on the Debug menu, or at an exception or at a breakpoint • On the Debug menu, choose Save Dump As. In the Save Dump As dialog box, specify a location and make sure that Minidump with Heap (the default) is selected in the Save as type list. To compare two memory snapshots To analyze the growth in memory use of an app, collect two dump files from a single instance of the app. By default, the memory analyzer filters the list of objects in a memory snapshot to show only the types and instances that are user code, and to show only those types whose total inclusive size exceed a threshold percentage of the total heap size. You can change these options in the View Settings list: Enable Just My Code Just My Code hides most common system objects, so that only the types that you create are displayed in the list. You can also set the Just My Code option in the Visual Studio Options dialog box.
On the Debug menu, choose Options and Settings. In the Debugging/ General tab, choose or clear Just My Code. Collapse Small Objects Collapse Small Objects hides all types whose total inclusive size is less than 0.5 percent of the total heap size. You can also filter the type list by entering a string in the Search box. The list displays only those types whose names contain the string. • For a type selected from the Object Type table, the Referenced Types tab shows the size and number of referenced types held by all objects of the selected type.
• For a selected instance of a type, Referenced Objects shows the objects that are held by the selected instance. You can hover over the name to view its data values in a data tip.
Circular references An object can reference a second object that directly or indirectly holds a reference to the first object. When the memory analyzer encounters this situation, it stops expanding the reference path and adds a [Cycle Detected] annotation to the listing of the first object and stops. Root types The memory analyzer adds annotations to root objects that describe the kind of reference that is being held: Annotation Description Static variable VariableName A static variable. VariableName is the name of the variable. Finalization Handle A reference from the finalizer queue Local Variable A local variable.
Strong Handle A handle to a strong reference from the object handle table. Pinned Handle An asynchronous pinned object from the object handle table. Dependent Handle A dependent object from the object handle table. Pinned Handle A pinned strong reference from the object handle table. RefCount Handle A reference-counted object from the object handle table. SizedRef Handle A strong handle that keeps an approximate size of the collective closure of all objects and object roots at garbage collection time.
Pinned local variable A pinned local variable. You can compare two dump files of a process to find objects that might be the cause of memory leaks. The interval between the collection of the first (earlier) and second (later) file should be large enough that the growth of the number of leaked objects is easily apparent. To compare the two files: • Open the second dump file, and then choose Debug Managed Memory on the Minidump File Summary page. • On the memory analysis report page, open the Select baseline list, and then choose Browse to specify the first dump file.
The analyzer adds columns to the top pane of the report that display the difference between the Count, Size, and Inclusive Size of the types to those values in the earlier snapshot.
