As the industry continues to grapple with the Meltdown and Spectre attacks, operating system and browser developers in particular are continuing to develop and test schemes to protect against the problems. Simultaneously, microcode updates to alter processor behavior are also starting to ship.

Now that microcode and patches are starting to ship, a clearer picture is emerging.
As the industry continues to grapple with the Meltdown and Spectre attacks, operating system and browser developers in particular are continuing to develop and test schemes to protect against the problems. Simultaneously, microcode updates to alter processor behavior are also starting to ship.
Since news of these attacks first broke, it has been clear that resolving them is going to have some performance impact. Meltdown was presumed to have a substantial impact, at least for some workloads, but Spectre was more of an unknown due to its greater complexity. With patches and microcode now available (at least for some systems), that impact is now starting to become clearer. The situation is, as we should expect with these twin attacks, complex.
