Will only installing this package speed up R?

According to this link, only installing the following package on Ubuntu will significantly speed up R for certain calculations:

libatlas3gf-base

Do I need to compile the source to get this benefit? If not, do I need to reinstall R after installing this package?

Are there any other packages like this, as they can speed up the process by just installing them?

The base package libatlas3gf-base will already help by default "reference blas", but you can (if you want) do better by creating Atlas locally. This to some extent means Atlas, since A and T stand for automatic tuning.

Now keep in mind that: a) rebuilding a package is not as trivial as just installing a basic package, and b) you were absolutely right in pointing out certain calculations. Your pure time spent in R will rarely be related to linear algebra operations, which you can speed up here. Therefore, for me, simply installing the atlas database is usually good enough for my Ubuntu and Debian systems.
