value. Physical DISK:CURRETN Disk Queue Length counter this value should not exceed 1.5~2 times the number of disks. To improve performance, you can increase the disk. Sqlserver:cache hit Ratio counter the higher the value, the better. If it lasts below 80%, you should consider increasing the memory. Note that the value of this parameter is incremented after starting SQL Server, so the value will not reflect the current value of the system after a period of time has elapsed. 47. Analysis Select
