Write Cache Hit Ratio (WriteCache)

This parameter displays the percentage of logical blocks written in the buffer cache. The write cache hit ratio indicates the effectiveness of system buffering. If you run I/O intensive applications and you have a large memory configuration, you may want to reconfigure your memory so that the write cache hit ratio is around 80 percent.
