New Thunderbird SLOW startup

Tue Mar 17, 2020 2:16 am

I ran an update today and now the new Thunderbird (1:68.5.0-1~deb10u1+rpi2) is starting very slow (45+ seconds). It and Lightning were the only two updates. The previous version started in about 15 seconds. I tried a command line start and it did not spit any errors. Did a reboot and no change.

Any words of wisdom would be appreciated.

Thanks

I too am having a horrible time with thunderbird locking up my RPi4B running Raspbian Buster 4.19. I have had to control F1 to reboot my computer. I reported this to the thunderbird team months ago and it has only gotten worse. Where can we get support for this app that I use on a daily basis on my RPi4B desktop?

I want to share some progress I've made after posting this issue on Mozilla's bug report site, link below. I'm not sure if I was able to capture the data needed but provided what I could, based on their instructions. If Brad Q wants to join this, have at it. I am really impressed with the thunderbird app but this bug makes it so slow it's unusable. Trying anything to make it work!

I THINK you and I MAY be seeing two different things. For me once Thunderbird is up and running, it is OK. It is just that it takes long enough to start that I am beginning to think I did not hit the icon properly.

Edit:
I ran the updates this morning and no change. However, I did notice that my CPU usage held at 25% while it loaded. While I do not know how it was configured before, I am wondering if it went from being multithreaded down to just using one thread (core)? For me that would explain the increase in the time it takes to load and I doubt I push Thunderbird hard enough (while it is up and running) to notice the difference between using one core or all four.

I too think they may be the same in that startup is 25% CPU utilization but mine stays like that and the UI is frozen but still takes input after a few minutes. I also think I got the profiler to work but am not sure if it sees thunderbird from the firefox addon.

The other reason you may be experiencing a difference is because you don't have a calendar that goes back to 1996 that I think thunderbird gets overloaded with data. This is a guess based on when I change my .thunderbird folder to one with no account, the performance is as it should be without all the calendar entries. Just a guess.

There was a notice that Thunderbird and the calendar (Lightning?) were separated into two units. So you MAY be seeing a Lightning issue and not a Thunderbird issue. OR it may be a linkage issue between the two.

I was told a while back that lightning is synchronous and that's what slows thunderbird from loading due to the calendar entries.

Well since I do not use the calender, I removed lightning. No change in start up time. I was actually surprised that apt did not want to remove Thunderbird with it.

Yes, same here without lightning enabled, long startup. I was able to generate a profile report that I hope helps find the problem.

I went back to a backup copy of Arch Linux ARM 4.19 to see how well it works and there is no degradation during startup and the calendar works fine. So from my limited testing, it appears there is a bug in Raspbian Buster 4.19 that causes the delayed startup of Thunderbird, regardless of calendar. Go figure.

In desperation I have temporarily installed the Ubuntu version of thunderbird 1:68.4.1+build1-0ubuntu0.18.04.1 which installs perfectly and works well . Otherwise one can return to the old raspbian version 1.60 which oddly exists in testing repo. If you have not yet upgraded then issue sudo apt-mark hold thunderbird.

I, too, experiencing the same slow startup since the upgrade from 1:60.9.0 --> 1:68.6.0 on my Pi-4B-4GB. The latest upgrade to 1:68.7.0 still has the same slow startup problem. Is there any workaround other than downgrade to 1:60.9.0?

On my notebook running Linux Mint 19.3 (Tricia), Thunderbird mail 68.4.1 (64-bit) startup immediately without problem.
