New subject: [Pharo-dev] Spur Garbage collection takes 4 times more when loading MSE (WAS: mse loading looks slower :()

What should we use instead? Array? nil when it’s empty? How about introducing some sort of
a NilDictionary?

Would anyone like to experiment?

Cheers,
Doru

 I think the use of SmallDictionaries for storing Famix state is not such a good idea.
After loading the model:

 bag := Bag new .
 SmallDictionary allInstances do: [ :each | bag add: each size ].
 bag sortedCounts

 "{530387->0. 19253->3. 18292->1. 20->2. 2->4. 2->11.
1->12}"

 bag := Bag new .
 SmallDictionary allInstances do: [ :each | bag add: (each keys) ].
