I think they are different. IMO, performance improvement is the time or memory reduction to some degree. This kind of change can be user visible (10 min -> 10s) and can be user invisible (2s -> 1s). > There already is a level of interruptability, the only change is in degree > of responsiveness. > > We*can* start adding such things to NEWS, but we don't do so today. > Before we start imposing this on everyone, we'll need to establish > what does and does not qualify - I'm guessing we don't want to add > a NEWS entry for every little performance improvement. However, this change isn't performance improvement, because it doesn't shorten the time of operation like "b 'foo.c':bar". This change only makes GDB more interruptable during some operations, IMO this is a good news to users and we should let them know. Regarding to NEWS entry for performance improvement, I don't have an opinion on it. -- Yao (齐尧)
