Site Origin Editor plugin is really slow when I'm writing

Hi,

I have a big latency/slow issue when I’m writing while I’m using Site Origin text editor. Everything is up to date (wp 4.4.2 page builder 2.3.1). I tried with chrome and firefox, and I also put my php memory from 40 to 256M without any result.

Thanks in advance for your help!
