# Hardware researcher spins up 'CPU deoptimization' project to find the slowest single x86 instruction, creates hall of shame — worst offender takes 198 billion cycles spanning 62 seconds to execute

> To optimize how software runs on hardware, instruction latency analysis looks at the time it takes for low-level instructions to execute on a processor, either to optimize the architecture or to optimize applications to…
