WebAug 15, 2024 · The “query_time_in_millis/query_total and fetch_time_in_millis/fetch_total” command can be used to determine the average time spent in each phase. Our cluster had a 40%–60% split between the average time spent in the query and fetch phases. This indicated that we could likely optimize the time spent in the fetch phase. The instruction cycle (also known as the fetch–decode–execute cycle, or simply the fetch-execute cycle) is the cycle that the central processing unit (CPU) follows from boot-up until the computer has shut down in order to process instructions. It is composed of three main stages: the fetch stage, the decode … See more The program counter (PC) is a special register that holds the memory address of the next instruction to be executed.
