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。

We cannot pay attention to read cache hit rate since we have been sequentially scanning a huge table over and over.

由于我们一遍又一遍地顺序扫描一个巨大的表，这样我们就无法关注读缓存命中率。

This means the cache can service the read requests instead of the database.

这意味着缓存是为读请求服务，而不是数据库。

Of course, the exploit that they've actually released is completely harmless, but it demonstrates that the CPU cache can be "poisoned" to let folks read and write into the otherwise protected SMRAM memory.
