The problem he is referring to is utorrent checking the state of the torrent files on startup. For people with torrents that have a lot of files, this can be time-consuming. This issue was introduced in r21575, when we fixed the problem people were having with ut adding ".!ut" to the end of completed torrents. At program start, we check the "started" state. In the case that this torrent is not started, we added a call to verify the have list of the torrent files, to set the completed flags on the file entry objects for that torrent. It was be tempting to use the "completed on" time as a hint whether to do the verify or not, but we didn't do it that way for reasons of how the !ut extension code works. We added a fix to mitigate this problem in r23344, by eliminating the disk checks when stopped torrents are added from the resume list on startup. This change also avoids an extra file check if the suffix is already correctly set. So, no-one should see this problem unless they have *active* torrents with many files. btw, we need to overhaul the .!ut extension code, but we've got many higher priority tasks at the moment. Adam
