Instructions/Request

The following graphs calculate and compare the instruction per request for web-search between x86 and ARM Architecture using two methods:

1. Using the formula (inst/req = inst/cycle * cycles/second * seconds/request) We used average latency to get the estimate for seconds/request.
2. Just calculating inst/requests.

Using the formula

Directly using number of instructions / total requests

The following are the graphs and data which was used to generate the above. They are in the same format as this page.
