Hi. I'm using claws-mail with IMAP. While most folders open instantly, some folders take ages to open: INBOX, Spam and some random subfolder of another folder seem to be the only impacted ones. When in debug mode, I get those in the logs: imap.c:1584:trying to fetch cached /home/jerome/.claws-mail/imapcache/domain/address/Folder/5357 imap.c:1594:message 5357 has been already cached. file-utils.c:58:TIMING safe_fclose : 0s068ms procheader.c:197:generic_get_one_field: empty line I have no idea why it only happens with those three folders. This has been an issue for quite a while (years, I believe, at least for INBOX folder). I just managed to solve the case of Spam and the other folder by renaming the folder and creating a new one with the same name. The new one is not affected, even after I copy the messages from the old one to the new one. Unfortunately, I can't rename INBOX. I tried to empty INBOX by moving messages into a temporary folder (using the UI). The tmp folder would open instantly. I then closed claws-mail and removed the dotfiles (.claws_cache and .claws_mark) in INBOX but as soon as I put the messages back from tmp, the issue reappears. I also tried to close claws-mail, delete INBOX folder from imapcache, then launch claws-mail. claws-mail recreated INBOX folder and redownloaded the messages from the server and the issue still persists.

Needless to say, this is a bit of an annoyance, especially considering the INBOX folder is the one affected. Anything I could try to solve or workaround this? Thanks.
Sorry, I just realized I already filed another bug reported a while back https://www.thewildbeast.co.uk/claws-mail/bugzilla/show_bug.cgi?id=4228 BTW I removed all plugins.
In Preferences -> Other -> Miscellaneous -> Metadata handling, I just checked "Faster". I still get the log lines shown above for INBOX and not for other folders but it is so much faster that it is viable. About a second to load INBOX with 200 messages, still noticeable but not a real issue anymore.

Out of interest, what filesystem do you use?

I use ext4 for both / and /home (where the email files are stored). # <file system> <mount point> <type> <options> <dump> <pass> # / was on /dev/md0p2 during installation UUID=xxx / ext4 errors=remount-ro 0 1 # /home was on /dev/md0p3 during installation UUID=xxx /home ext4 defaults 0 2 While I'm happy I can now open my inbox pretty fast, I'd call this a workaround. It could still be noticeably slow if the inbox contained more messages. Also, there is something going on that I don't understand. Why the "trying to fetch cached" messages in the logs? How come it only happened on 3 folders and I managed to remove them by just recreating the folders? I'm wondering if removing the whole account from my machine and creating a new one would "solve" the INBOX case.
