Game will frequently freeze for .5 seconds when looting mobs

I have a pretty decent computer:

AMD Radeon R9 390, I run WoW on my SSD with 800gb free of space, 8 gigs of ram etc. Yet, when I loot my game will freeze very briefly. This isn't a huge issue but it is certainly annoying.

Though, this did only start happening when I reinstalled it to my SSD. On my harddrive this did not occur. Any ideas why? This is on the Wotlk client.

disable all of your addons and check if it still happens

Yup, still happens. I even tried renaming the WTF, Chace and Interface folders so they reset upon game launch and the problem still occurs
