Meltdown patch reduces mkfile(8) throughput to less than 1/3 on OS X
Can someone who is more familiar with Meltdown speculate on this? Is this a quick fix and is it likely to be optimised over time and become less slow? Or is this the raw trade-off and current hardware will always suffer slow-downs to this degree. Can an OS be rearchitected in ways that would mitigate the performance loss?
