Does using the built in encryption option cause any degradation in performance?

Do you mean full Hard drive encryption? Other than a slightly slower boot up time  ( a few seconds at most ) no.

Fortunately, the built in one only encrypts the /home partition, not root or Swap. :)

 

Unless anything has changed from the last time I installed Mint 18, 2-3 weeks back. Most any type of encryption of any OS (example, Bitlocker) will also slow the boot time, unless one has a smart card reader inserted or pressing on a fingerprint reader at the same time as hitting the Power button. And I can't promise that.....may have to wait until asked for before performing either. If performance by encryption were a widespread issue affecting many Linux users, we'd be hearing of it more, as there's more business professionals who are running Linux versus the consumer market. 

 

A huge example of this is the #1 Linux distro in Ubuntu (by Canonical). That corporation has field offices all over the World to get businesses to subscribe to Ubuntu, tailored to their needs. Us end users are merely testers of the professional product, by submitting bugs & making suggestions, bugs are fixed ASAP, suggestions for features are read, though may or may not be incorporated into any release. 

 

I have three TPM enabled devices, and all are LInux compatible, however the workarounds required made me go against the idea on Linux Mint, just use to lock down some USB drives or externals with important content with the non-Linux OS, not all that that I have, nor any partition on my computer. If I need a Linux file encrypted, will zip & send to the non-encrypted partition of the external, then encrypt when I log onto the OS with Bitlocker. 

 

Of course, if I were a business professional with lots of valuable data on a notebook, I'd use any encryption method available to me, which ever one I feel the most comfortable to use & will secure the data properly w/out backdoors, even at the price of a slightly lowered boot time and/or performance. :)

Performing full disc images weekly and keeping important data off of the 'C' drive as generated can be the best defence against Malware/Ransomware attacks, as well as a wide range of other issues.
