Wild fuzzy handwaving offering of direction follows . . .

You're probably not going to get really accurate times as the SVN client itself doesn't provide that information. You might could use Expect or IPC::Run to open a pty which is reading from your svn co URL process and use Time::HiRes to note duration between when lines for each file are emitted (you'd want to make sure it's on a pty so that its STDOUT hopefully doesn't go into buffered mode). After the checkout is done you'd go back and compute the rate by looking at the final size of the file (but keep in mind that SVN keeps another copy of the current revision's contents stashed locally so there's probably some extra time for the local copying embedded in those values).

If that's not precise enough you might want to look at the swig interface to the underlying SVN API; however I don't know if you wouldn't wind up rewriting most of svn co in order to get things instrumented at the right places to get the numbers in which you're interested. Not to mention the SVN API's kinda hairy at the lower levels . . .

Also something like File::Magic could be of interest in determining what kind of contents files have.
