i agree with michael. at the end thre's the following:

Intel's current selection of integrated graphics processors (IGPs) are
already slow when it comes to just the hardware, but with the graphics
stack currently found in the Ubuntu 9.04 development branch the
performance is simply miserable. The performance drops were nearly
across the board with both 2D and 3D regressions being very
noticeable.


it's said that the actual stack found in jaunty is miserable, which is
different from
saying that intel stack is miserable. on the other hand, jaunty hasn't
been yet released
in beta so it's clear that there would be some major issues.
these tests prove that jaunty isn't there for the use of normal users
but not that intel's
new stack is not ok. i'd suggest people to read more carefully before
spitting out
something not true, that the original part hasn't been saying.

also, i think that these git tests are better run on a gentoo (or a
gentoo based distro) box,
since it has a much better way of handling different package versions,
especially the ones from git.
