configuration with internal_overflow_size/leaf_overflow_size (explicit configuration of the size of an overflow item. Fix a bug where we never actually paid any attention to the internal overflow item size, even though we set it. Delete the split_min debugging configuration string: the problem is that small pages now have to be set in concert with the overflow size, if there is an overflow size that's relatively large, and we create a split page smaller than an item which is itself smaller than the overflow size, the item will never fit on the page and we loop forever. I haven't chased any bugs in reconciliation's page size in quite awhile, hopefully split_min is no longer interesting. Write a basic performance tuning page for the documentation. --HG-- extra : rebase_source : 0825ab4ff58b2dcb18675290f299fad0f5eaaae7
