I’m having some issues with Thunderbird. It’s running really slowly and making my whole computer lag. Thunderbird consumes constantly 8-9% CPU while it’s on. I’m using Windows 11 and Thunderbird version 128.4.3.esr (64-bit) on a laptop with fast NVMe drives.
I’ve added 8 email accounts, and the mail folder (Roaming/Thunderbird) is about 165 GB right now. I think it’ll go over 200 GB once all the messages finish downloading.
The problem seems to be with message indexing. The Activity Manager shows it’s indexing over 300k messages. Even if I leave Thunderbird running all night, it doesn’t finish. When I get new emails in the morning, the indexing starts all over again. It takes hours and uses a lot of CPU while it’s happening.
If I disable the "Enable Global Search and Indexer" option, Thunderbird works fast and smooth, and CPU usage drops a lot. But, I assume, this means I lose the ability to search emails.
When the lagging happens, opening an email preview can take up to 3 seconds (!), and deleting a message also takes 2-3 seconds. However, when I disable the "Enable Global Search and Indexer" option, Thunderbird works ultra-fast. Opening and deleting messages is instant, and there’s no delay.
Any idea how to fix this?
