To the point you really need specialized knowledge.

I remember DrDobbs and The C/C++ Users Journal having ads for companies whose sole product was a memory allocator for different kinds of deployment scenarios.

And those products really did help. Microsoft's implementation of malloc performed terribly for many workloads - dropping in a 3rd party allocator could speed up your software considerably.

It wasn't until well into the 2000s until the standard allocators started to become good enough to make the 3rd party libraries less essential. Many of them you can still buy today and they probably still help with certain types of software.
