Neomutt time to time: Fetching message headers... about neomutt HOT 5 CLOSED

Sometimes the structures that we cache in the header cache change and this invalidates the cache. We don't retain the old structures in the new code. We don't have a better way to migrate an older cache to a newer version. In my opinion, a full invalidation is the safest solution (cache coherency is hard). This is definitely not a bug. At best, the experience could be improved, but I doubt we have developers' time and interest in doing it.

Uhum i see...

But very annoying when I update the program and at first start a have to wait more then 15 minutes, when neomutt refetch all headers.

And after some day, when i open "sent" messages folder an another suprising "coffe break".

Not a bug... but "this one just sucks more" :).

I see you use gdbm. See if performance increases using lmdb.

Now I switch to ldbm.

I try to measure the time of "fetching header" but at the end of the counting, neomutt said: "Unable to open mailbox..." the time: 8min and 45sec

I start again: neomutt start to fetch messages headers again... and that time everything is o.k.. Now the time was about 4min.

IMHO the fetching is more "costly" than the performance of local storage...

Yeah it can definitely be, depending on your connection with the IMAP server.
