I’m getting this problem too with Yoast 3.5. I had a slight problem already, but then after we upgraded to the new readability analysis it got a lot worse. WP is almost unusable now and everything takes an excruciatingly long time. I’m the only one at my company having this problem so I suspect there’s something on my machine that’s conflicting with Yoast content analysis but I can’t figure out what. I have two macbook pro 2011 with 2.5GHz, 16 GB memory running OS Sierra 10.12 and the problem happens on both machines in both safari and chrome, but does not happen in any other online typing platform except WP. Additionally, it does not happen on my own private WP site, which does not have Yoast installed. It would be incredibly useful if I could temporarily disable real time content analysis. Unfortunately I don’t have access to that level of control at my company. It would be great if there was some kind of toggle (at my level) to turn off the real time feature while I’m typing, then turn it back on at will.
