Hi
This difference in runtime is gone now that the binary has been built on
the same
toolchain as the from-source compile. The binary/PPA runtime is now 12.5
seconds
on a laptop CPU (negligibly close to the 11.5 seconds on a desktop CPU).
So the runtime slowness seem related to the Ubuntu 10.04 b
The next version of ATLAS will have "generic" presets which will be used
e.g. if throttling is enabled. This should greatly reduce the risk of
mis-tuned ATLAS installs.

What is tuned on one host can be mis-tuned on another. Nothing strange
about this.
Perhaps a binary ins
A 20x speedup seems to be a bit too good to be true. It could be that the
binary has a botchered (mis-tuned) ATLAS install. I guess its possible to
have that kind of speedup, but only with very specific problems that
immensely profit from SSE3/4/AVX.
