Adobe Reader very
slow in opening pdf files.
Adobe Reader’s 100% cpu usage while opening a pdf file will
slow down your computer to a crawl.
For example, the screenshot above shows that opening a
single pdf file starts four AcroRd32.exe processes, one of which is consuming
91% of the cpu and frequently goes to 99%.
Adobe Reader vies with Adobe
Flash in providing one of the worst user experiences.
These Adobe Reader issues have been around for quite some
time with no fix. Adobe seems to be ok in continuing to deliver a terrible user
experience.
A few solutions online to make Adobe Reader
faster are to change the Reader configuration as follows.
1. Disable Adobe Update
Edit > Preferences >
Updater
Select Do not download or install updates
automatically
2. Disable Protected Mode at Startup
Edit > Preferences >
General
Uncheck Enable Protected Mode at
startup
3. Disable Enhanced Security
Edit > Security (Enhanced)
Uncheck Enable Enhanced Security
Change 2, 3 at your own discretion as they may make you more
vulnerable to malware
delivered via pdf files.
