Im trying to speed up a very slow app where sync times can sometimes exceed a minute. So I tested the App in various ways to try and see if there was any difference. What I found was that the Delta Sync option makes a MASSIVE difference. With sync times for an already open app being typically only about 20% of the sync time when opening an app from scratch. But thats not the issue iโm reporting.
So after doing this I went into the Performance profile to find the slowest and then drill down to see what I could find. I didnโt get that far. What I think Iโve found is that the manually timed syncs I did and the figures quoted by Performance Profile are VERY different. Performance Profile is reporting sync times at about 20%-25% of what they actually took.
Ignore the hour difference, that due to British Summer Time
