Very slow loading of search folders
When I click on a search folder it takes a really long time to load. Although the folder has around 120,000 messages in it, when I run Evolution from terminal with all the debugging flags enabled there does not appear to be any IMAP transactions pending during the load. So it doesn't appear to be a server issue.
Sometimes the folder loads in only a second or two, and other times it takes a minute or longer after I haven't clicked on it for a while.
I am using Evolution 3.34.1.
I noticed this fellow from a few years ago is having a similar issue.
