Thunderbird runs much better on Dell 5590 than on Blackbird
« on: November 11, 2020, 12:51:25 pm »
Hi,

Thunderbird on my Blackbird often freezes for a few seconds during which I have to wait patiently, while on my Dell Latitude 5590 notebook it runs much smoother. Here are the two setups:

Blackbird SW: Thunderbird 78.0.4 64 bits runs directly on the host (Fedora33 - kernel-5.8.18-300)
Blackbird HW: Power9 v2 4 cores, 32GB and two SSD M.2 disk (128 and 256GB)

Dell SW: Thunderbird 78.3.1 64 bits runs on a VM (2 vCPUs and 400-4000MB RAM); host running Qubes OS R4.0 (updated to the last minor version), Linux 4.19.152-1 with Xen 4.8.5-25-fc25
Dell HW: Intel i5 8th gen, 16GB RAM and 512GB SSD M.2 (pretty average specs)

My suspitions:

1. The Thunderbird port to ppc64el is not optimized for the architecture, relative to the x86 version. Do not take me wrong, no complains. I'm thankful to whoever ported it.
2. My /home logical volume on the Blackbird (where Thunderbird stores my mail boxes) is split between the two physical disk, which in turn are each connected to a different PCI slot.
3. I have this feeling that after upgrading Blackbird from F32 to F33 it got worse.

Any feed-back is appreciated.

On which task does Thunderbird freeze? I never observed such behavior.

It's not related to compacting mails. It looks like it gets slow/freeze every time it syncs with the servers and updates my many folders.
