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. WebFetch the contents of the memory location pointed to by the PC. The contents of this location are loaded into the IR (fetch phase). IR ← [[PC]] Assuming that the memory is byte addressable, increment the contents of the PC by 4 (fetch phase). PC ← [PC] + 4 Carry out the actions specified by the instruction in the IR (execution phase).
