Clicking any message loads it instantly, searching through my 30000 emails in 10 different accounts is also instant, etc. Why is my experience so different? Mostly everything is on default settings.&lt;p&gt;Pretty much the &lt;i&gt;only&lt;/i&gt; complaint I have about this tool is that parts of the window sometimes flash for seemingly no reason when it is left open for a while.</text><parent_chain><item><author>formerly_proven</author><text>&amp;gt; “Why does Thunderbird look so old, and why does it take so long to change?” ~ A notable percentage of Thunderbird users&lt;p&gt;Honestly this doesn&amp;#x27;t seem like the main issue with Thunderbird; the main issue is that the UI is very slow, it tends to use a lot of CPU and memory just sitting there and a lot of operations block the UI.

I remember it was crazy fast, especially real-time search folders were a game changer for me, so I could filter messages however I liked and let them appear in multiple folders without affecting performance.&lt;p&gt;I haven&amp;#x27;t used it in a while, but if it&amp;#x27;s true, it&amp;#x27;s a pity that once so useful and fast piece of software deteriorate so hard. One would expect that a stale project can only benefit from the newer hardware to become crazy fast ...</text><parent_chain><item><author>formerly_proven</author><text>&amp;gt; “Why does Thunderbird look so old, and why does it take so long to change?” ~ A notable percentage of Thunderbird users&lt;p&gt;Honestly this doesn&amp;#x27;t seem like the main issue with Thunderbird; the main issue is that the UI is very slow, it tends to use a lot of CPU and memory just sitting there and a lot of operations block the UI.
