Ask HN: Disk Encryption for Mac OS X

Hello,

I have a Mid-2014 13" Retina MacBook Pro 2.6GHz Intel Core i5 with 8gb memory + SSD hard drive running 10.10.3 Yosemite.

I was using FileVault 2 included in OS X by default for full disk encryption, however, the performance was absolutely abysmal. Does anyone have any alternative suggestions or suggestions on how to make FileVault actually a reasonable option?

kernel_task was consuming 80-150% of cpu power on a regular basis and was simply slamming my otherwise rather powerful machine.

Thanks!
