Default High Sierra poor CoreAudio performance

I've recently updated two machines from Sierra to High Sierra. After things settled (Spotlight, etc.), I had to raise my latency to get rid of drop-outs that never were there before. Now it only works at 256 spls, but used to at 64.

I see same on both computers, both with USB and Thunderbolt interfaces. I see this both in Reaper and Studio One. Somehow this upgrade worsened my audio performance, though nothing else had changed. I've tried deleting CoreAudio preferences, I've tried the "delete the disk and restore 10.13 from Time Machine" path, etc. Nothing helped yet.

Did anyone had a similar problem? Or High Sierra is good and stable for you in that department?
