However, using the excellent PerfView tool we can capture the full call-stack of any memory allocations, that is any calls to VirtualAlloc() or RtlAllocateHeap() (obviously these functions only apply when running the CoreCLR on Windows). However the part that I’m going to look at for the rest of this post is the memory that is allocated by the CLR itself, that is unmanaged memory that is uses for all its internal data structures.īut if we just look at the VMMap UI view, it doesn’t really tell us that much! If you’re interested, the rules for heap or more specifically segment sizes are helpfully explained in the Microsoft Docs, but simply put, it varies depending on the GC mode (Workstation v Server), whether the process is 32/64-bit and ‘Number of CPUs’. Only the Committed memory is actually being used, the total Size is what the GC pre-allocates or reserves up front from the address space. In addition, note the difference between the amounts in the Size and the Committed columns. The main thing to note about the image above is that you can clearly see the different heap, there is 256 MB allocated for Generations (Gen 0, 1, 2) and 128 MB for the ‘Large Object Heap’.

The next largest usage of memory is the GC itself, it pre-allocates several heaps that it can then give out whenever your program allocates an object, for example via code such as new M圜lass() or new byte. ‘Managed Heaps’ created by the Garbage Collector

Note: If you want to find out more about memory usage in general, but also specifically how measure it in. However, to get a more detailed view, we will now look at the snapshot from 2 seconds into the timeline, when the memory usage has stabilised. The HelloWorld program just prints to the Console and then waits until you press, so once the memory usage has reached it’s peak it remains there till the program exits.

It’s called VMMap and it’s part of the excellent Sysinternals Suite.įor the post I will just be using a simple HelloWorld program, so that we can observe what the CLR does in the simplest possible scenario, obviously things may look a bit different in a more complex app.įirstly, lets look at the data over time, in 1 second intervals. NET Profilers available such as dotMemory by JetBrains or the ANTS Memory Profiler from Redgate (I’ve personally used both and they’re great)įortunately there’s a fantastic tool that makes it very easy for us to get an overview of memory usage within the CLR itself. Note just to clarify, this post will not be telling you how you can analyse the memory usage of your code, for that I recommend using one of the excellent. I mean the memory that the CLR itself allocates, all the internal data structures that it needs to make is possible for your code to run. via new M圜lass(.) and the Garbage Collector (GC) then cleans up. NET Runtime (CLR) allocates memory? I don’t mean the ‘ managed’ memory that your code allocates, e.g.
