When my Acrobat runs in the background for a while, I open the pdf file will be very slow, it may take more than 20 seconds.

Hope you are doing well and sorry for the trouble. As described the Acrobat Reader is slow in opening the PDF files.
Is this a behavior with a particular PDF file or with all the PDFs that you try to open? If the PDf is stored on a shared network/drive please download the file to your computer locally and then try to open it and check.
