Hmm... on my laptop it's less than half that, and allnoconfig takes ~35s, so clearly there's a major difference between our setups. For reference, which distro are you using, and what is /bin/sh on your box? > Um, no. Just no. Please find a way to make this overhead go away. Will do. Trivially, switching to diff -q halves the check runtime for me, and I'm sure there are other parts of the scripting which can be optimized. Thanks, Mark.
