I have been trying different OSs on my Raspberry Pi2 B. I have found that the Ubuntu Mate 15.04 OS seems to be running faster and software is more responsive than when I have Raspbian installed. I particularly notice a big difference between Firefox on Ubuntu and the Raspbian supplied browser or Ice Weasel. I have not overclocked the RaspPi2. Is this because Ubuntu uses the hardware of the RaspPi 2 better than Raspian does? Or is it just that Ubuntu's Firefox and software are better versions than say Ice Weasel?
Is there a way to make Raspbian more responsive? Would over clocking help speed it up? Compared to Ubuntu Mate, Raspbian seems to lag. I like Raspbian and would have not noticed had I not tried Ubuntu on the RaspPi2.
