Span

tl;dr Use Span to work with ANY kind of memory in a safe and very efficient way. Simplify your APIs and use the full power of unmanaged memory! Contents Introduction Introduction C# gives us great flexibility when it comes to using different kinds of memory. But the majority of the developers use only the managed one. Let’s take a brief look at what C# has to offer for us: Stack memory - allocated on the Stack with the stackalloc keyword. Very fast allocation and deallocation. The size of the Stack is very small (usually < 1 MB) and fits well into CPU cache. But when you try to allocate more, you get StackOverflowException which can not be handled and immediately kills the entire process. Usage is also limited by the very short lifetime of the stack - when the method ends, the stack gets unwinded together with its memory. Stackalloc is commonly used for short operations that must not allocate any managed memory. An example is very fast logging of ETW events in corefx: it has to be as fast as possible and needs very little of memory (so the size limitation is not a problem). internal unsafe void BufferRented(int bufferId, int bufferSize, int poolId, int bucketId) { EventData* payload = stackalloc EventData[4]; payload[0].Size = sizeof(int); payload[0].DataPointer = ((IntPtr)(&bufferId)); payload[1].Size = sizeof(int); payload[1].DataPointer = ((IntPtr)(&bufferSize)); payload[2].Size = sizeof(int); payload[2].DataPointer = ((IntPtr)(&poolId)); payload[3].Size = sizeof(int); payload[3].DataPointer = ((IntPtr)(&bucketId)); WriteEventCore(1, 4, payload); } Unmanaged memory - allocated on the unmanaged heap (invisible to GC) by calling Marshal.AllocHGlobal or Marshal.AllocCoTaskMem methods. This memory must be released by the developer with an explicit call to Marshal.FreeHGlobal or Marshal.FreeCoTaskMem. By using it we don’t add any extra pressure for the GC. It’s most commonly used to avoid GC in scenarios where you would normally allocate huge arrays of value types without pointers. Here you can see some real-life use cases from Kestrel. Managed memory - We can allocate it with the new operator. It’s called managed because it’s managed by the Garbage Collector (GC). GC decides when to free the memory, the developer doesn’t need to worry about it. As described in one of my previous blog posts, the GC divides managed objects into two categories: Small objects (size < 85 000 bytes) - allocated in the generational part of the managed heap. The allocation of small objects is fast. When they are promoted to older generations, their memory is usually being copied. The deallocation is non-deterministic and blocking. Short-lived objects are cleaned up in the very fast Gen 0 (or Gen 1) collection. The long living ones are subject of the Gen 2 collection, which usually is very time-consuming. Large objects (size >= 85 000 bytes) - allocated in the Large Object Heap (LOH). Managed with the free list algorithm, which offers slower allocation and can lead to memory fragmentation. The advantage is that large objects are by default never copied. This behavior can be changed on demand. LOH has very expensive deallocation (Full GC) which can be minimized by using ArrayPool.
