>>> dicts_128 = operations.filtersize(dicts, 128)

The biggest chunk of dicts are 128 byte dicts. Furthermore, from dicts_128.txt we can see that many of them are empty! A quick grep shows that there are 20854 empty dicts. This means empty dicts are using 2669312 bytes of memory. Let's find out where they're being created.

>>> empty_dicts = {}
>>> for key in dicts_128:
...     if dicts_128[key].obj == {}:
...             empty_dicts[key] = dicts_128[key]
...
>>> empty_dicts_creators = annotate.findcreators(empty_dicts)
>>> formatting.printsizes(empty_dicts_creators.back, count=10000)
