Memory optimization guide in Unity 6

While this guide has some decent profiling and memory optimization tips, I was puzzled by the claim that Unity GC can compact managed memory blocks.

I even went to recheck the official documentation to verify that Unity still uses Boehm GC for both Mono and IL2CPP scripting backends, and it is a non-compacting GC.

So I discussed this topic with ChatGPT, and it gave me the same claim about the compacting algorithm until I referenced official documentation in the chat. It's sad that a guide from such a well-known website with various valid tips is still affected by AI hallucinations and false claims (btw, if what the post claims regarding the compaction step is valid, then share links to the GC implementation or any docs, I would love to update my knowledge).

Apart from that AI slop, the tips are valid and can be used to optimize your runtime memory.
