Yes, this is the interesting point in this thread. If you take an "old" release, on any platforms where we have "old" releases available, and do a side-by-side comparison with the latest release, we may well have a performance regression. However the possible performance regression is not documented in technical terms. People have mentioned a slowdown in previous threads, but nobody posted any numbers. Last time, a video was posted, but that link is no longer working and I'm not sure if it had numbers in it. Last time it was discussed I did generate numbers myself and then solved the problem. However that discussion was focused around Sugar startup time. This discussion now turns to activity startup time. So, having someone generate activity startup time numbers in a fair test (i.e. same platform, different software versions) would be of value. If there is a performance regression here, we don't have a technical diagnosis that I know of. It seems like some people suspect GTK3/gobject-introspection as the cause, and those may be likely candidates, but I don't think we have real diagnosis supporting that (yet), nor any explanation for why those new technologies might be slower than the old ones.
