Description

I have two profiles. The first one backs up really critical stuff to my BorgBase remote repo, the second one backs up my entire home directory to a NAS in my home network. Switching between those profiles takes a long time - about 25 seconds. During that time, the program window is unresponsive, Kubuntu greys out the window and says that Vorta "does not react" and offers me to kill the process.

Unfortunately, I can't pinpoint the exact version of Vorta where this issue occurred the first time. I believe it was introduced when the profiles were moved to the left side of the window, but I might be wrong.

Here is a screencast to show how long it takes (Repo location blurred out, of course): https://youtu.be/xVuywsOY4Go?si=yousLqS0vgW8sPF7

###### Only now, the profile was actually switched, and I could interact with Vorta again.

This is extremely slow in your case. I also noticed a delay after recent updates, but it's only 1-2s.

It will re-populate the info in all the tabs on profile change. I guess one of those is a bit slow with too much data. (many logs or archives?)

many logs or archives?

The BorgBase repo has 86 14 archives and a total amount of 8.07 7.92 GB actual data on disk (deduped).
The NAS backup (Sophos) has 34 archives and a total amount of 1 TB actual data on disk (deduped).

I just noticed that the remote backup did not prune properly for some time now, I edited the numbers above accordingly. The video was recorded with 86 archives in the BorgBase repo.

Switching from Sophos to BorgBase is now considerably faster (about 6 seconds, which I find acceptable). The other way around (BorgBase to Sophos) takes about the same time.

What seems strange to me, however: The visible GUI changes instantly, but you cannot interact with it. For example, I have the "Archives" tab open and click on another profile. I can instantly see (a maybe cached/outdated??) archive list of the profile I switched to, but cannot interact with Vorta at all during the (now 6 second) load time. As a DAU (aka "stupidest user one can think of", as we say in Germany 😉 ), I'd assume once something is displayed, I should be able to interact with it.

Personally, I don’t mind these 6 seconds, but it might be a symptom of a bigger problem/opportunity for improvement, so feel free to close this issue or leave it open. I don't know anything about Vorta code, so I leave this decision up to you 😉

Switching from Sophos to BorgBase is now considerably faster (about 6 seconds, which I find acceptable). The other way around (BorgBase to Sophos) takes about the same time.

Actually, the time is not always the same: It still goes up to 20-30 seconds sometimes. I tested it multiple times now and got varying results, all under the same background load (8 open tabs in Firefox, Dolphin, Kate and KDE system settings open).
I can't spot anything unusual in the logs when switching profiles, only the Added item number X from Y statements as seen above.

Output of free -h at this time:

Will do some debugging later to see if there are some easy wins to be made.

Found the following:

  • In one instance we populate 2 tabs twice, which is not necessary. Fixed this already.
  • Additional slowness comes from getting mount points. This calls an external command.
  • Finally, populating the Wifi list takes some time. I tried to keep all items and only update them, but it was still slow.
  • If a profile has many archives it's also slower. Talking a few hundred.

Wifi and Archive list both use the same widget. Maybe there is a better way to insert items into it. Still looking into that and will push a PR after.

Couldn't get the Wifi list faster with batch inserting or updating existing items only. So the only way is to use a worker thread for the list. We already do this for folder stats (FilePathInfoAsync).

I'm close to fixing this by moving the Wifi- and mount processing to separate threads. After this, the GUI updates aren't as blocking: #1964 (comment)
