It is already done for each package, at installation.

What version of R? This is much faster in recent versions, including R-devel. The latter takes only 3 seconds on my system, with 1500 packages installed. It is likely the problem is reading the package indices on your system, especially if they are on a non-local or slow file system. Note that subsequent queries in the session make use of the already-built database (if relevant).
