Installed Windows on second HD (SSD), now extremely slow

I installed my new SSD as a secondary internal hard drive instead of SuperDrive and tried to install Windows 7 on it this way and it's now extremely slow and unusable.
I opened Bootcamp assistant and created Windows USB. Then it recognized that I have a second internal drive and I clicked continue. It created BOOTCAMP partition on SSD and restarted but went nowhere.
Then I read online that certain Macs don't boot off USB and that the drive you install on has to be in the main hd slot. So I put my SSD drive in the main hd slot and put the optical drive back. Then I booted through Windows 7 install CD and installed Windows on SSD. Everything seemed to be fine and I was able to boot to Windows.
I took the optical drive out, put SSD in its place and put the original HD back to original spot.
Now I am able to see Windows and OSX through REFIT and can boot into Windows but it is extremely slow and always freezes. I actually think that OSX became slower too.

Not sure if this was the correct way to install it so any suggestions are welcome.
BTW the SSD drive is brand new, so I highly doubt that it has issue.
I believe it's 2011 Macbook Pro.

Does anyone have any clue what's going on?
My goal is to have OSX on original drive and Windows on a second SSD drive.

Well, you did it the way it will work. Windows by default will not install in the optical drive slot due to anti-piracy prohibitions by Microsoft. The only way to get it work is the way you did it.

How did you install the OS X drivers for Windows 7? Part of the Boot Camp procedure is to obtain drivers from Apple by using the latest Boot Camp software for your Mac. Without the Apple drivers, Windows 7 will not function correctly. Probably why Windows 7 freezes and is sluggish.

It was slow even before installing the drivers. But I also thought that this might be the problem and used my old drivers that I downloaded in the past (which did not include this new hard drive). I'll try to install new drivers to see if it helps.
I will also try to switch places of the two drives and see if that makes a difference, I read somewhere that this could be the issue for some reason.

Switching sounds a better idea. Your MBP comes with 6GB/s in the hard drive position, and could be 3GB/s in optical drive slot if it is the early 2011 model.

So I swapped the two drives and it works properly now. I guess the optical slot is slower.
