Constructing a lot of small objects - performance, memory fragmentation

Hi I’m curious that if this kind of action causes memory fragmentation too.
Does anyone knows how Unreal handle memory allocation?
I haven’t study the source code but I guess UE is using some kind of pre-allocated memory pool, so there should not be any fragmentation issue, is it?

Unfortunatly, a pre-allocated memory pool doesn’t prevent memory fragmentation. It can help lower it, but it’s not a cure.
