I turned FireVault on for my brand new iMac 5K and at first, everything seemed to be working smoothly. After a week or so, I started to notice that my system was responding very slowing waking up from sleep and login into my user account. I also started noticing other strange slowdowns that seemed to happen randomly. At first, I thought I may have installed faulty 3rd party RAM from Crucial, but after doing some research, I found that some users reported that FireVault was causing similar problems to what I was experiencing. Sure enough, I turned off FireVault and the problems stopped. I like the idea of FireVault for an added layer of security, but the performance issues and glitches were very frustrating. What's the consensus...is FireVault faulty by nature? Are people using it knowing that it slows down their machines and causes problems? Or was I doing something wrong?
