Security Adobe Reader XI is the most secure version Adobe has ever released
This is primarily due to the new Protected Mode, which loads potentially dangerous elements and code in a sandboxed area isolated from the rest of the system.
Speed There has been much criticism of Adobe Reader’s speed compared to other lightweight PDF readers
This is true; Adobe Reader comes with more plug-ins and extensions than most PDF readers, which can slow it down.

However, the difference for the average user is negligible, and these add-ons can be disabled if they are not needed.
Later releases also worked to improve the memory usage of Adobe Reader, making multitasking less of a burden on the system
