I figured some such simple fix would be possible. Please install your fix. What my experience has taught me is that cases of anomalous gross slowness often have a simple fix. Thus, before taking up the difficult question of whether major surgery is justified, it's a good idea to look for a fix like this one which does the job with a band-aid. (Yi-dong found a different way to apply a band-aid, but it assumes that the file was visited in Image mode, so it doesn't solve the whole problem. This change does, I think.)
