in reply to More questions than observations on installman

Am I reading this right, or ignoring something obvious?

That is the way I read it as well.

I took a look at installman , here are some ideas I had for making it faster

Rewrite it so it doesn't use no_chdir, because that is supposed to be slower
File::Find::find({no_chdir=>1,
You can also get rid of this stat (-f), because there are no directories in perl/lib or perl/pod , that end in .pm or .pod
if (-f $_ and /\.p(?:m|od)$/) {
Hmm, actually, you might be able to get rid of File::Find altogether by caching the file list perl\pod\buildtoc generates

But, I doubt you could make a significant dent in the runtime with these simple ideas (I guesstimate 10 seconds), due to OS level file system caching .

What would probably work better is making Pod::Man->new happen in a few threads

Oh, and I didn't even look at Pod::Simple::BlackBox :)
