how to use net memory profiler

the memory is a piece of continuous memory. The following figure shows the status of a managed heap before and after a garbage collection: We can see that GC not only clears memory that is not in use, but also moves other objects in the memory to compress the

Once a member of a struct type is declared, the layout order of the members in memory in the instance is determined by the same order as the member declaration, and is always aligned by default to the member with the largest space in the structure (Align). And, of course, we can set or encode the way memory is aligned.In. NET managed environments, however, the CL

when assigning valuesThis is one of the most significant differences between a value type and a reference type: A variable of value type directly obtains a true copy of the data, whereas assigning a reference type is simply assigning a reference to the object to the variable, which may result in multiple variables being referenced to an object instance .(2) Differences in memory allocation　　objects of the reference type will allocate

Now some. NET developers began to discard the asp.net built-in caching mechanism, instead using memcached--, a distributed memory caching system, originally developed by Danga Interactive for the LiveJournal site. A fundamental problem with caching is how to handle obsolete data. When running on a separate Web server, you can easily clear a cache that has been confirmed to have been changed. Unfortunately,
