I have lots of multiprocessing processes which have to add to and search in a dict. Deletion of values is not needed.

Atm I am using multiprocessing.Manager() and

dict = manager.dict()

This works pretty well, but I think that the manager is a huge bottleneck here. Any ideas? It has to run on older Python 3 versions, otherwise I would use this cool thing I found: https://github.com/ronny-rentner/UltraDict
