Recently I make an ubuntu oneiric fresh install, but it is deadly slow. My computer is a HP Pavilion AMD Phenome X3 8600 with 3GB RAM and GeForce6150SEnForce430 according to Nvidia x server.

So I make a few reads, and maybe the slowness it is because the HW, but I'm not an expert, but I installed 64 bit and I think should be faster that if I installed 32 bit version, right? so the problem must be something else, Am I right?

My english is far from perfect, I'll hope you can understand. Thanks you all in advance

Update
+ with unity 2D is faster
Update
+ The test's result suggest by Kelley gives me yes.
