Struggling with data extract/integration performance after enabling DSO

While testing DSO in FCC, our integrations are taking much longer to run (5x to 10x longer). We have extracts/integrations that utilize the following:

1) Pulling upper-level, dynamic Account members - these are fairly easily resolved by pulling level 0 descendants instead, but could be troublesome in the future depending on what we need to extract based on new requirements

2) Pulling upper-level, dynamic Movement members that were previously Stored (such as FCCS_ClosingBalance and FCCS_Mvmts_Subtotal). These are causing us particular trouble, as even if I try using level 0 descendants, it still takes a lot longer than it used to (5x to 10x longer)
