Chosen Solution
15 inch MacBook Pro with 4 GB of RAM memory running sierra operating system. After waking up, sometimes takes minutes for applications to free up for use. Is this a result of not enough RAM? Will upgrading to 16 GB of RAM improve performance?
What is happening is the hard drive is reading from the swap and writing it back into the RAM. If you upgrade to 16gb, it actually may take longer. I would suggest upgrading to a hybrid SSD or full SSD drive to improve this issue.
