In this article, we will learn about the different types ofmemory management techniquesand also the pros and cons of different memory management techniques. 1. Contiguous Memory Allocation Incontiguous memory allocation, all the available memory space remain together in one place. It means freely ava...

Despite the techniques described here, over time the pattern of allocation and free may result in fragmentation of the variable-size heap. For embedded systems, it is best practice to pre-allocate all memory requirements for applications at the time of startup and subsequently manage the allocated...

The TWS represents your app’s full impact on the system, so the measurement techniques I’ll describe will use this number. However, when tracking down potential issues, you may find it useful to investigate the private or shared working sets separately, as this can tell you whether it’s...
The Other Data category represents calls to a primitive OS memory allocation function (VirtualAlloc) that VADump cannot categorize in any other way. For .NET applications, typically the most important component of Other Data is the garbage-collected heap that holds all user-defined objects. ...
Modifying the default settings is useful if the load pattern includes spikes. When there are sudden spikes in the processing load, the report server might go from no memory pressure to memory allocation failures quickly. This result might occur if you have multiple concurrent instances of a memory...

Single contiguous allocation is one of the earliest memory management techniques. In this scheme, RAM divides into two partitions: Operating system partition. A partition is reserved for the operating system. The OS loads into this partition during startup. ...
