First at all Im not responsible for any bricks at all. This application involves some risk but it uses some tweaks that you'll only find in a custom rom. Here it is the link:

In my own opinion it improves your device performance and it gives you a hand cleaning out dalvik cache and cache, also it has a lot of performance and battery tweaks.
You need to be rooted and busybox has to be installed for the application to run ok, and I strongly suggest that you have cwm installed just in case you need to fix a soft brick.
In my case I had no soft brick issues at all but I wouldn't put my hands on fire.
