“In my opinion, one area where successive Ubuntu releases
continuously under-performed is on the overall system performance
front. Every new Ubuntu release feels more and more bloated,
especially so with latest Ubuntu 11.04 Natty Narwhal. I was quite
taken aback by fact that, even the so called Ubuntu “derivatives”
like Pinguy OS and Elementary OS were a lot slicker than the
original Ubuntu. Having said that, Unity is still very young and I
believe it will become vastly improved by the time of next Ubuntu
LTS release. But what all can we do to significantly improve
overall performance of Ubuntu Unity right now? Lets explore.”
