634+ Few notes on performance
635+ ------------------------
636+ 637+ ``.wire() `` utilize caching to speed up the wiring process. At the end it clears the cache to avoid memory leaks.
638+ But this may not always be desirable, when you want to keep the cache for the next wiring
639+ (e.g. due to usage of multiple containers or during unit tests).
640+ 641+ To keep the cache after wiring, you can set flag ``keep_cache=True `` (works with ``WiringConfiguration `` too):
642+ 643+ .. code-block :: python
644+
645+ container1.wire(
646+ modules = [" yourapp.module1" " yourapp.module2"
647+ keep_cache = True ,
648+ )
649+ container2.wire(
650+ modules = [" yourapp.module2" " yourapp.module3"
651+ keep_cache = True ,
652+ )
653+ ...
654+
655+ and then clear it manually when you need it:
656+ 657+ .. code-block :: python
658+
659+ from dependency_injector.wiring import clear_cache
660+
661+ clear_cache()
662+
