> Speculative execution in general is a sizable performance boost that brings in the risk of all sorts of attacks like this. Makes me wonder when we will start seeing physical two-tier architectures, a complete but slower, safety centric system for handling sensitive data on both OS and application level and a souped up "you have been warned about potential leaks" OOE system acting as a general purpose accelerator addon. The difference to existing security enclave concepts would be that the less safe side would be the add-on.
