请问DBD中如果两个wrapper list会不会性能更好

现在DBD里只有一个wrapper list，modify后台修改完了需要拿锁等待所有读锁释放；如果wrapper list也分前后台两组是不是这里会更快一点？

Start by locating the DBD implementation and the code paths for the single wrapper list, modify, and read-lock handling. Investigate whether separating foreground and background wrapper lists is feasible and measure the effect on lock waiting; done requires a documented decision supported by performance evidence.
