(In reply to Paul L from comment #14) > Perhaps, then, this bug should be left open but with less priority until > further performance improvements can be found? Is it this bug or a more general one that typing in a label is too CPU expensive?
On the 1 GHz machine typing a character into one of 1500 labels takes 75% even with Karaoke closed. It takes 65% even with one label, but with one label there is no performance impact. With 1500 labels, no Karaoke, 75% usage, it takes 1 second for the typed character to appear. With 1500 labels, karaoke, 100% usage, it takes 2 seconds for the typed character to appear. There is an old resolved bug 406 for label (and other) slowness where I think the only changes made were to reduce the amount of autosaving. However that alone made a dramatic improvement. It looks like redrawing less of the track panel was not attempted. I note that typing a character in an almost empty text document produces a 90% spike on the 1 GHz machine. So perhaps this is not really anything to worry about.
