At work we use Adobe Reader to view and print PDF file. At home I mostly use one of the open-source PDF viewers, though I have installed the closed-source Adobe Reader application for Linux. The problem with Adobe's Reader application is that it's SO SLOW, which is very noticeable on Linux where I have much faster alternatives.
Long ago I found instructions from Adobe to remove most of the plug-ins and low and behold Reader started much faster. I had forgotten to do this on my current work system and never even tried with Reader for Linux. This week we were updating quite a few PDFs on the company website so the delay for Reader to start was becoming a pain, so again I disabled the plug-ins and again Reader now starts acceptably fast.
