I know, this doesn't answer your question, but why don't you move your operating system over to your SSD instead (note: You probably shouldn't do this if your SSD is smaller or equal to 64GB)? That would offer a way bigger boost in performance (especially in the boot department).
Actually I don't see why moving the temp folder would give you any performance boost whatsoever... even if you were talking about the pagefile, which apparently you aren't...
Usually SSDs offer their own utility to move your os over to it, otherwise reinstalling Windows also works. I would suggest you to search for the benefits of having your OS stored on your SSD online, so you don't have to rely on one single opinion. I'll say this much, it is totally worth it.
Thank you for reading my post. I hope you understand my "English".
