"Saving application details" takes a long time.
From the forum:
I’ve just timed it on my device (a Sony Xperia Pro, so getting on a bit). The download takes about 3 seconds, the processing 1 to 1100-ish takes another 3 or so, and the checking apps compatibility takes another 3 or so. That’s fine, and from memory is how it was a version or two ago.
But it now also takes about 20 seconds to do “Saving application details”, so the whole process takes about 30 seconds. I notice, by the way, that it always pauses for a second or two at 33% – presumably there’s an app at that point that has a lot of details that need to be saved!
I'm creating an issue for this so that I can investigate in the future if there is any way to improve this process. The time it takes to save the apps will scale linearly with the number of apps in the index. So in the future, when there are 2000 apps in the index, it will take almost a minute for some people to update their index.
