- In FieldLoader, cache boxed bools and some boxed ints.
- In FieldLoader, presize collections when parsing a List, HashSet or Dictionary.
- In FieldLoader, don't allocate a list of missing items until required.
- In FieldLoader, when a string value is passed, avoid wrapping this in a MiniYaml object by allowing both strings and yaml to be passed in the GetValue overload that does the real work.
- In Animation, avoid allocating no-op actions.
- In VxlReader, use EnsureCapcity to better size the Dictionary.
- In VxlReader change VxlElement to a struct.
- In Locomotor, presize TerrainSpeeds dictionary.
- In MixFile, the Distinct call doesn't presize the HashSet it uses internally. As we know we will enumerate all results, create the HashSet ourselves so that is it presized correctly.
- In ObjectCreator, stream the assembly when hashing rather than reading all bytes into memory.
These changes avoid some allocations on the large object heap, in turn this means the GC can avoid performing unnecessary Gen 2 collections just to clear down the LOH.
This avoids loading, parsing and merging YAML rules for the mod during loading of each individual map. This saves significant time resolving custom rules on each map loaded.
# Example Scenario
MockString:
CollectionOfStrings:
StringA: A
MockString:
CollectionOfStrings:
StringB: B
MockString:
-CollectionOfStrings:
MockString:
CollectionOfStrings:
StringC: C
MockString:
CollectionOfStrings:
StringD: D
# Previous MergePartial result
# The CollectionOfStrings is merged into a single unit, so the C and D items are dragged upwards and jump ahead of the Removal
# When this is processed, the final result removes CollectionOfStrings entirely
MockString:
CollectionOfStrings:
StringA: A
StringB: B
StringC: C
StringD: D
-CollectionOfStrings:
# New MergePartial result
# When merging nodes, we no longer allow merges to jump an intervening removal node.
# This means we can have multiple of a certain key (CollectionOfStrings in this example) which was not the case previously.
# When this is processed, the final result includes C/D but not A/B.
