Code size analysis#

pw_multibuf: A buffer API optimized for zero-copy messaging

The following table shows the code size cost of using pw_multibuf. These size reports compare a fake MultiBuf implementation against the v1 and v2 pw_multibuf implementations, and also compares the two pw_multibuf implementations against each other.

The scenarios being measured involve sending and receiving data using a fake protocol stack. At the lowest layer, “DemoLink” frames carry “DemoNetwork” packets, which in turn carry segments of a “DemoTransport” message. This layered protocol demonstrates how different MultiBuf implementations can handle data encapsulation and fragmentation.

The v0 implementation uses simple, contiguous spans of memory, requiring data to be copied at each protocol layer. In contrast, pw_multibuf is designed to avoid these copies. It allows for reserving space for headers and footers, and can represent data as a collection of discontiguous memory chunks. This reduces memory usage and improves performance by minimizing data movement.

The key difference between pw_multibuf v1 and v2 lies in their approach to memory management. Version 1 integrates memory allocation directly, with a MultiBufAllocator that handles the creation of MultiBuf objects. Version 2 separates memory allocation from the buffer logic, allowing users to provide their own allocation schemes. Additionally, v2 introduces the concept of “layers” to more explicitly manage different views of the data, such as protocol layers.
