Debian has provided optimised Atlas libraries, compiled as shared libraries,
for over eight years. So not everybody sees this as 'silly'. We set up our R
builds to transparently use them.  That way you'd get tuned linear algebra as
a plug-in -- and the plugin is made possible because of the shared-library

So not everybody agrees with BDR's resolute statement implying static-only
builds if one is concerned about performance.  Performance is almost always
relative, and often relative to several possibly conflicting baselines.


Three out of two people have difficulties with fractions.
