Slow loading localhost (browsersync problem?)

Heya. I seem to be having a similar issue as this older topic, with the difference being that Sage now uses Webpack and not Gulp.

Still, it’s a similar thing. Reloading the front page on the Trellis .test TLD is reasonably quick (although I’d like to see that even faster than the ~2 seconds it usually takes) but when I’ve yarn started and going through Browsersync on localhost:3000, I’m recording at least 6.5 seconds on every reload - sometimes more. Am I expecting too much, or is this abnormal behaviour? I just started up this project, so there are no extra plugins aside from ACF and no content or assets added yet.

I’m having very slow yarn start load page reload times as well.
Closer to 15-20 seconds, actually. yarn build time is about half that.

Anyone have suggestions on how to begin troubleshooting?

@neptunus Ever get your problem worked out?
