Summary
In this chapter, we jumped into the world of low latency application C++ development. We built some relatively fundamental but extremely useful building blocks that can be used for a variety of low latency application purposes. We put into practice a lot of the theoretical discussions related to using C++ and computer architecture features effectively to build low latency and highly performant applications.
The first component was used to create new threads of execution and run the functions that different components might require. One important functionality here is being able to control the CPU core that the newly created thread gets pinned to by setting the thread affinity.
The second component we built was meant to avoid dynamic memory allocation on the critical code path. We reiterated the inefficiencies associated with dynamic memory allocation and designed a memory pool to be used to pre-allocate memory from the heap when constructed. Then, we added utility to...
