I gave Unity a good chance, but it was simply torture. Maybe it’s the over 3 years old hardware I’m running Ubuntu on, or maybe it’s the servers I’m running on my machine for the project I’m working on, but the hard drive kept thrashing to a point where it was unbearable. Sometimes just clicking a top menu or switching to a different window would take over a minute while the hard drive was grinding as if it was being benchmarked.
So I decided to go back to Gnome classic. The computer is way more responsive now and works considerably faster. My guess is that either Unity’s memory requirements are so high that I ran out (of 2 GB) and the memory had to be constantly swapped or it’s my relatively old 3D accelerated nVidia video card or Unity is doing too much disk access. Whatever it is, Unity does not work well on my machine.
I’m not so happy about reverting back to Gnome because I don’t like to be the kind of person who doesn’t accept change. But for the sake of productivity – I have to forget about Unity for now.
