Has anyone else noticed a 10X slowing of the time it takes Thunderbird to load an email that contains graphics on CentOS 6? The last Thunderbird update moved us from Thunderbird 45 to Thunderbird 52.
While Thunderbird was loading the images the hard drive was busy cranking out seeks. I have all my local home accounts mounted on a software raid.
I solved the problem with a downgrade to Thunderbird 45, but that's a poor solution not keeping Thunderbird up to date with the latest security patches.
