After waiting for Ubuntu 9.04 release date, and 15 hours upgrading from Ubuntu 8.10 to Ubuntu 9.04, I was disappointed with Ubuntu 9.04’s performance. Ubuntu 9.04 is much slower in performance compared to Ubuntu 8.10. And after googling a while, it looks like I’m not alone. I found this thread complaining about Ubuntu 9.04 performance. So what happened to Ubuntu?
First, after installation, I tried to explore what’s new in it. But what I found was a big disappointment. Sometimes an application freezes, especially when I want to close Mozilla Firefox 3.0.9, it freezes and I need to force quit, argh….. Then I felt it was a lot slower when trying to change windows between applications, there is a delay of approximately 1 second to change windows and tabs in Mozilla Firefox. And this didn’t happen in Ubuntu 8.10. Now I have to turn off some Compiz animations so it will be a little bit faster. And other applications also have the same performance problem, it really dropped.
Second, boot time is slower than Ubuntu 8.10 — with all the same startup processes it takes 3-4 minutes to boot. Third, it also consumes more CPU and memory resources. My PC specs are Intel Pentium Core 2 Duo 2 GHz with 2 GB of RAM and an onboard video card.
I don’t feel comfortable using current Ubuntu 9.04 Jaunty Jackalope. Should I downgrade to Ubuntu 8.10 Intrepid?
How about you?
