This is my kind of research share.google/YKi09RDock3T...

share.googleHardware 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 executeIronically, new advanced instruction sets could make for even slower commands.
