I just confirmed that it is the bind variable peeking, causing the optimization to be delayed to the Execute phase, that was causing the long Execute time. Simple test - I just ran the statement with literals instead and then the Parse phase is long and the Execute phase drops to 0:

call count cpu elapsed disk query current rows
------- ------ -------- ---------- ---------- ---------- ----------

---

Parse 1 11.19 11.94 0 0 0 0
Execute 1 0.00 0.00 0 0 0 0
Fetch 2 0.00 0.00 0 342 0 21
------- ------ -------- ---------- ---------- ---------- ----------

---

total 4 11.19 11.95 0 342 0 21
