If 100% Buffer and Procedure cache hit ratio is considered not good in general?
I check Buffer Cache hit ratio with below query and it showing 100% (100.0000000000000)
SELECT (a.cntr_value * 1.0 / b.cntr_value) * 100.0 as BufferCacheHitRatio FROM sys.dm_os_performance_counters a JOIN (SELECT cntr_value,OBJECT_NAME FROM sys.dm_os_performance_counters WHERE counter_name = 'Buffer cache hit ratio base' AND OBJECT_NAME = 'SQLServer:Buffer Manager') b ON a.OBJECT_NAME = b.OBJECT_NAME WHERE a.counter_name = 'Buffer cache hit ratio' AND a.OBJECT_NAME = 'SQLServer:Buffer Manager'
Are there instances that it is actually bad and can contribute to server performance degradation? I want to know how much of Buffer and Procedure Cache hit ratio is reasonable to have normal SQL server?
