Any jailbreakers with iPhone 4?

I noticed that my iPhone 4 got really slow and crashed a lot when I had Winterboard installed. Then I updated to 6.1.2 and jailbroke again, but this time I didn't install Winterboard and my phone feels more or less fine.

So it got me wondering, how are other people's iPhone 4's holding up. Have you noticed any tweaks in particular slowing your phone down a lot? Or maybe someone knows a workaround to this issue I'm having?
