Performance Analysis of DBLE vs MyCat: Identifying Sorting and Isolation Level Issues

A detailed case study investigates why DBLE middleware achieves only about 70% of MyCat's performance, revealing that excessive sorting CPU usage, a cmp‑function inefficiency, and a delete‑loop bug under REPEATABLE_READ isolation cause the slowdown, and demonstrates how adjusting isolation levels and fixing the cmp implementation restores expected performance.
