Ulatency - Better performance?

There is ulatency package in the Trisquel 7 repo. Has someone tested it and can that software improves a system performance? Inert use cfq I/O scheduler by default but it can be changed to bfq that is as default in Trisquel. How about prelink and preload? Should I also use them in the same system? I use 3.13.x generic kernel version at the moment.
