Ubuntu Kernel Performance

[Victor Polukcht]

Hi all. I'm using Ubuntu for a couple of years, and all that time i was
using Intel-based Laptops. First that where P-3 based machines, last one
is Pentium-M machine with 1G RAM and i915-based video (64M RAM). Some
time ago i got AMD64-based desktop. After some upgrades it is quite
modern AMD64-3200+ Socket AM2, 2G RAM DDR2, Nvidia GeForce 6200 256Gb,
SATA2 HDD and also Edgy Eft running on it. You want to ask why am i
describing my desktop and laptops configuration? The answer is: My not
very modern laptop is working much faster than amd-based desktop. I'm
using binary Nvidia drivers on it, so that shouldn't be a weak point.

I took a look at default kernel configuration that comes with linux-386
kernel, and found that it has enabled i486-optimization options. Can it
be the reason of my troubles?

The only way i'm asking this question is my desire for understanding
what should i do next, throw away my new desktop, or recompile kernel
and so on.

PS: I don't want to install 64-bit version of Ubuntu until there
wouldn't be normal support of flash animation and all other things i
need.

Thanks in advance.
