• Serialize and Deserialize array 2000 item

	Type	Size	Deserialize	Deserialize GC	Serialize	Serialize GC
FlatBuffer	binary	2.846	0.0528	0.2485	0.2745	0.7279
MessagePack-Csharp	binary	1.000	1.0000	1.0000	1.0000	1.0000
JsonUtility	text	2.657	0.0793	0.6279	0.0341	0.3851

• Searching item MemoryMaster is faster than FlatBuffer

• find item have id 1746 in array 2000 item

var item = Find($"Id_1746");

	Find	Find GC
FlatBuffer	1.76ms	335B
MemoryMaster	0.7ms	48B

• find each item once in array

for (int i = 1; i < 2000; i++)
{
    var item = Find($"Id_{i}");
}

	Find	Find GC
FlatBuffer	34.4ms	254.5KB
MemoryMaster	4.17ms	179.2KB

• JsonUtility has many limits as:
  • not support array (you need write class helper to support this)
  • not support dictionary (you need custom class which acts as a dictionary item or using other custom serializer)
  • the float value serialize is not accurate due to the encoding problem. You can change float to string to get an accurate value.
  • not support binnay search as part of itself
