# FFI 缓存优化
用于 tick、循环、事件回调等性能敏感路径中的 FFI 调用。
规则:
- 高频 FFI 调用优先考虑缓存
- 大容器、大对象、配置、状态快照不要每次都跨语言重新取
- 用事件、脏标记或版本号驱动缓存刷新
- 变化频繁且必须实时的数据,再直接调用 FFI
- 缓存策略要和数据更新源绑定,避免无效刷新
- 不要为了性能过度增加状态复杂度,仅在高频需求下使用这类优化
原因:
- FFI 调用有跨语言边界成本
- C/C++ 侧构造大容器并转换为 Python 对象开销高
- 热路径重复拉取同一批数据会明显拖慢吞吐
- 过度缓存会提高维护成本并增加状态同步风险
反例:
```python
for _ in range(100000):
entities = list(serverApi.GetEngineActor())
```
案例:
```python
_WORLD_ENTITY_CACHE = []
_NEED_REFRESH = True
@Listen("AddEntityServerEvent")
def AddEntityServerEvent(_=None):
global _NEED_REFRESH
_NEED_REFRESH = True
@Listen("EntityRemoveEvent")
def EntityRemoveEvent(_=None):
global _NEED_REFRESH
_NEED_REFRESH = True
def GET_WORLD_ENTITY_LIST():
global _NEED_REFRESH, _WORLD_ENTITY_CACHE
if _NEED_REFRESH:
_NEED_REFRESH = False
_WORLD_ENTITY_CACHE = list(serverApi.GetEngineActor())
return _WORLD_ENTITY_CACHE
