Could you tell me more about synccompare?

In the syncevolution.org packages, it is under /usr/bin/synccompare.
It's a perl script that takes two database dumps and compares them,
similar to a diff between text files.

I find it to be of variable usefulness. It is great when it works, but
in my experience it scales horribly.

I just use it on a laptop and it works for me, but I agree that it's
mostly a hack originating in the automated testing. There's even a bug
open for rewriting it...

I think I always see "comparison was impossible" with refreshes. I
assumed that is because the databases are deleted or something (although
thinking about it further I am not sure that is a reasonable expectation).

There should be "before" and "after" dumps also for refreshes, so this
has to be something else.

So what is the goal of this command? Does it mean that something went wrong but nothing important enought to break the system?

I deleted the two related to my configuration, restarted to clear the sessions and then added again my notes taken from there http://influence-pc.fr/03-07-2015-synchroniser-ses-contacts-et-calendrier-dubuntu-phone-via-owncloud-cosy-cloud (was working from past 2 years) so just after the first "sync slow" here is what I can see:

Even if I delete the config, the backup database still contain entries!
