Recently I have changed my hard disk to SSD to speed up Thunderbird process. BUT! as you can see the process above, Thunderbird used 100% of CPU
What cause it ?
The answer is, too much email in one folder. I just have to archive everything and there is alot of improvement in term of speed and CPU usage
