I just recently upgraded to Ubuntu 10.10 from 10.04 through a fresh installation and noticed that the boot was extremely slow compared to 10.04. My hardware specs-

2 GHz Dual Core
2GB memory
(Acer 4730Z)

While booting there's also an error message saying some thing like-
No wubildr [but after that it boots properly, but slowly ]

Do you recommend to move back to 10.04 or is there anything I can do about it?
