So Tom's is speculating that the hulabaloo regarding slowdowns is overstated.

A note of caution: The bug will have an impact on some programs, but the chance of a widespread 30% reduction in performance is slim. Phoronix conducted testing on the patched Linux 4.15-rc6 kernel with an Intel Core i7-6800K and an i7-8700K. It tested applications that are confined to the user space, which are typically indicative of what you would see on a desktop system, and found that these applications "should see minimal change (if any) in performance." That means you will likely see little to no performance impact on your next desktop session, be it gaming or otherwise...
...The performance impact is more pronounced in PostgreSQL, which is an open source object-relational database system. PostgreSQL has issued a warning about performance regression that includes benchmarks showing a 17-23% reduction in performance with the new patch. Redis also appears to suffer a performance loss, but to a lesser extent.

So yeah, data farms will see a hit but the day to day user probably won't even notice. Still sucks.
