Granted, I haven't used inotify in such a situtation, but it probably won't use much CPU. That would be driven mostly by how you choose store/retrieve the latest information. We could be talking about a bunch of memory though. So this would probably be exchanging speed and disk io for memory. This all depends on the parameters that we (us being not Wayne) don't know about the situation. leif
