What "similar effects" do you have in mind? "mem_pool" may have more than one "effects" to multiple things that are affected, but it is unclear which effect that "mem_pool" exerts on what you are referring to. > Using the new memory pool API may be more beneficial > to our memory management in the future. Many things may or may not be "beneficial" in the future. We do not build things on a vague "hunch". Are you seeking performance (e.g. number of objects that can be allocated per minute)? Are you seeking better memory locality (e.g. related objects are likely to be stored in the same page, reducing number of page faults)? Are you seeking reduced wasted memory (e.g. custom allocator packs objects better than bog-standard malloc(3))? Are you seeking functionality (e.g. you have this and that specific codepaths and usecase where you wish to be able to release all the objects instantiated for a particular repository, without having to go through the list of all objects, and use of mempool is one way to allow us do so)? It is not even clear in your problem description what kind of benefit you are seeking, let alone how much quantitative improvement you are getting with this change.
