[Borgbackup] performance problem

No problem, just finish it somehow, even if it runs over the day.

Maybe your first backup will not be super consistent (as at daytime,
people will change files). But it will transfer most data chunks to the
repository and create a files cache, so it can be faster next time.

Keep the first backup at least until you finished the 2nd backup of the
same data.

It might take longer the first time, but (assuming that most of your
data is not changing and also the files cache of borg is working
normally), your subsequent backups will be way faster than the first one.

It is, just not the first time.

Unless your 2nd backup is also unexpectedly slow, there is no big problem.
