i installed 11.04 today, in one of my powerfull machines (AMD Phenom 64 quad), but, the performance in 64 bits is so poor.... too heavy, too mucho disk access, i am not happy. i preferr the previus 10.04 release, more faster, more powerfull.

my machine has 8 gb dd3 memory.

i wait some day for patches fixing this performance problem, if not fixed, i will be returning to 10.04.
