CPU performance isn't important for 'typical home and business' tasks. They're estimating 6% slowdown based on SYSmark 2014. I quickly skimmed the whitepaper and think this is probably reasonable; there's a mix of CPU-bound and I/O-bound tasks, and the CPU-bound tasks won't be impacted. Most home users are still on spinning disks, so that's your bottleneck for I/O, not the additional syscall overhead. A 6% slowdown is imperceptible to a human. For tasks that don't need a lot of CPU power (like office applications and web browsing) even a 30% slowdown is not that big a deal.
