My iMac is too SLOW when I use Publisher

[Printery]

Hola everybody. I am Novo in Affinity. I know is my fault. What option I choose, that is making my iMac like a Commodore? Beside been only 79, my blood pressure told me to ask about this. Any help will be appreciated.

What is your iMacs specs? CPU, GPU, RAM. What OS are you running?

Is it slow all the time or only when you have a job open?

I would still like to know when it is slow. If you open a blank single page document does Publisher move sluggish and laggy? Or is it when you are working on a particular file? I found Publisher to get bogged down the bigger the document, but my test files were 400 page document and 1000.

I am seeing the same issue in Affinity Publisher and I never see this when I'm using Affinity Photo.  At this moment I notice this when I am exporting to PNG.  It literally takes 10-15 minutes for the dialog to show up when I select export.  No other applications are running.
