Oneiric is giving me a really bad performance at the moment and and I want I go back to a faster Ubuntu version. Would 10.04 give me a good performance??
its not about Ubuntu, its about the fancy stuffs that are now being shipped with Ubuntu. Then kernel per-se is pretty fast enough.
If you have used the custom version of Ubuntu, Ubuntu Ultimate UE, you can notice how worse it performs compared to the standard installation.
So, ya 10.04 would perform better than 11.10 since many fancy things like 3D graphics won't be burning your CPU cycle.
I personally think that Canonical has been declining in performance of Ubuntu steadily, 8.10 was better than 9.10, which was better than 10.10 which again was better than 11.10. But this is only a personal opinion. I have no data to back up my claim.
You can get a feel of what I said at this page which is comparing 8.10 and 9.04.
