What is the fastest (to access) struct-like object in Python?

Question

I\'m optimizing some code whose main bottleneck is running through and accessing a very large list of struct-like objects. Currently I\'m using namedtuples, for readability

Answer 1

I would be tempted to either (a) invent some kind of workload specific caching, and offload the storage and retrieval of my data to a memcachedb-like process, to improve scalability rather than performance alone or (b) rewrite as a C extension, with native data storage. An ordered-dictionary type perhaps.
