If it was as easy as pointing a finger and saying "here optimize that," then it probably would have already been done. 90% of the effort in optimization is figuring out exactly what is slow and can be improved. So if you want to proceed into this -- pull out a profiler and start digging in. For example, take a UI operation you think is too slow, figure out a way to profile what is going on during that time, then analyze the results to see what can be improved.
And I will say, the kernel is perhaps not the meatiest place to look at for this work.
