A buffer get is simply an I/O request that didn't need to access the disk directly because the required buffer was still in memory.

My understanding of a buffer get is a request for data from a data buffer
(ex. DB_BLOCK_BUFFER) therefore showing an approximate amount of CPU
resources used, as every time a request to a buffer is sent it takes a CPU cycle.

Hi All

Could someone explain to me what is a buffer get.

I find Logical reads, Consistent gets, Physical Reads and have the impression that the combination of the first two is buffer gets but can't find evidence for it

Anybody?
