Read Cache Hit Ratio (ReadCache)
This parameter displays the percentage of logical reads that are in the buffer cache. You can use this parameter to monitor the effectiveness of system buffering. If you run I/O intensive applications and have a large memory configuration, you might reconfigure the buffering so that the read cache hit ratio is about 95 percent.
