Of course this does not say much, I did not measure anything, it's just my feeling, and apart from win in virtual-box the "heaviest" thing I do is resizing a video from my mobile using ffmpeg. The rest is some maria-db databases, digikam with large database and thousands and thousands of images and videos, gimp, internet with many open windows, some of them loaded with scripts. In all this I don't /feel/ any difference.
As Marcus said it probably depends on the workload and for sure soon there will appear serious tests, but for me with my common, manual desktop-use there is no need to be afraid of "tragic" performance loss.
Just be glad you are not google or amazon or the like that purchased 4000 16/32 core servers to handle the load (based on pre-Meltdown) processor capability (as well as determining the number of routers, patch panels, etc.) No you are a big data company and find out you cannot support your current customer base because you have just been told all of the data you built your hardware requirements from were 30% inflated and, now that after the failed speculative execution reload fix, the additional registers and needed instructions for cleansing the processor cache data will leave you with a system that is too-small by 1/3 to meet your business needs. Them's the ones that are going to feel the impact the most. For you, and just about every other desktop user where your system runs at .02 - .05 utilization, you probably won't notice much. Now gamers that make a bizillion system calls per-second will be much more likely to seem scenery drag. It will be interesting to see where the impact is felt the most. -- David C.
