Hi

1)The README in the distribution mentions using Durus for upto a million
objects? Is that number based on some empirical testing or observed problem
with more than that number?

Would you expect problems with a PersistentDict with say 450000 key/value
pairs?

2) is there any intention or need at MEMS to implement BTrees like ZODB?
Would anyone hazard a guess at how difficult/easy it would be?
