Hi,
I am experiencing really poor performance in the admin area (I am using visual editor). The main issue is uploading photos, I can literally take a few minutes break after hitting any update button (e.g. in Customizer) or when uploading 4MB worth of pictures (cca 10 photos, around 400kb each). The front end is ok (with caching). Can you please help me? What specifications of the server I need to get better response?
Thanks.
