Package: mutt
Version: 1.5.17+20080114-1+b1
Severity: normal
The versions of mutt after 1.5.17-1 do need much more time to initially
read a mail. Header caching is enabled. I did some testing with time and
strace. The folder I tested the stuff with is an maildir with roughly
37000 Mails.

| user 0m1.216s |user 0m1.324s
| sys 0m0.204s |sys 0m0.300s
With strace -r I found out that all the lseeks in version 15.17-1 added
up to 2.28s where they added up to 80.42s in the strace -r run with
version 1.5.17+20080114-1+b1. So lseek is responsible for quit all of
the difference of version 15.17-1 and the versions after it.
Both versions I tested used the same configuration files and I did
recreate the header cache for both version. For every test I did an
reboot to terminate OS caching mechanisms influence.
I mentioned this behaviour as an followup to bug #459739 long time ago
but since #459739 was closed the issue has fallen asleep. So here I am
again. :-)
With kind regards,
Dirk
