in memory. Dieter estimates 20% to 35% slowdown for the C algorithms (whatever that means), Tim seems to think it won't have such a big effect. I guess we'll only know after some benchmarks.
Can we please not make any definite decisions until this issue has been resolved, some of us do actually care about performance ;-)
Yes, ideally, I'd like to see just IIBTree's but only if there are not perfomance implications. I think BTrees sit low enough in the stack that it's perfectly justifiable to have both an I BTree and an L BTree.
If having two isn't acceptable, then why do we have an I and O BTree's, not to mention the special ones used for in-memory ZODB indexes? Surely we should just have one BTree class?
