Boot charting

I remember having read busybox was slow and that there was a patch for
this. So I googled around and this article came up:
http://tree.celinuxforum.org/CelfPubWiki/OptimizeRCScripts

It states:
# Each command including built-ins within pipes are forked.
# Each back-quoted command is forked.
# The 'echo', 'test', and '[' commands and other most frequent
commands in the scripts are implemented as applets.

And there are a couple of workarounds (including the affordmentioned patch).

I don't know how much this will turn out usefull.
