Help diagnosing lightnig performance issues

Hi there,

On my current machine, opening Lightning’s monthly view takes about 50 seconds. I have 4 calendar subscriptions, with about 50 events.

What’s the right way to profile Thunderbid to find the culprit?


What version of Thunderbird?

68.8.0; I’m on Linux Mint 19.3, which is based on Ubuntu 18.04

Clément, Sorry for the lack of reply.

Performance improvements are beginning, but they will be happening in version 78. So if you are not using the enigmail addon, I would encourage you to update late next week to 78.2.0 from
