Hello, everyone!

I have created an application where I need to store a lot of entities in a map.
The map will be accessed concurrently, so I have to decide between TMap or ConcurrentMap.
The point of confusion is as far as I know, If I will use TMap, the application may become memory intensive.
My end goal is to reduce the memory footprint as much as possible.
Could you please advice how to approach the problem?
