Because workloads with high Symmetrix cache read-hit rates are serviced at memory access speed, storing the data needed on EFDs may not result in a significant increase in performance.

因为具有高symmetrix缓存读中率的工作负载都是以内存访问速度实现的，所以在EFD中存储所需要的数据可能不会对性能有大的改进。

CICS TG on z/OS makes use of the EXCI to provide high speed cross memory access to CICS, a mechanism not available on other platforms as it is an MRO-based communications mechanism.

z/OS 上的 CICS TG 使用 EXCI 提供对 CICS 的高速交叉存储访问，这是其他平台无法提供的机制，因为它是基于 MRO 的通信机制。
