Hi,
I am running OpenBSD 4.4 i386. I have a 20 Gigabyte Mailbox inside my
Home folder in ~/mail/ in maildir format. Altogether there are about
148800 Mails inside. Yes its too big, and probably should be split up
better, but it is what it is, and occasionally i need to search trough
it for some old Information. For this i have installed mutt-1.5.18.
Here is my .muttrc , plane jane:
set mbox_type=Maildir
set folder=$HOME/mail
set spoolfile=+/INBOX
set header_cache=/faster/hcache/
set message_cachedir=/faster/bcache/
set check_new=no
set read_inc=1000
ignore *
unignore From To Cc Subject Date Reply-To Organization X-Mailer
If i now type `mutt` into my Terminal, mutt will take about 736 seconds
just to open up the Mailbox, displaying a "Reading
/home/ds/mail/INBOX...x/148800 (3%)".
`top` shows the CPU (P4, 3GhZ) working away at 60% or so, but vmstat -c
100 nor iostat -c 100 show much activity.
If i now add the Option unset maildir_header_cache_verify to my .muttrc
, opening mutt takes about 9 seconds, much much faster, so it seems my
maildir is very slow to stat.
maildir_header_cache_verify means : Check for Maildir unaware programs
other than Mutt-ng having modified maildir files when the header cache
is in use. This incurs one stat(2) per message every time the folder is
opened.
Can anyone tell me why this is? Does this have to do with our Filesystem
and that there are a lot of files in a directory, or is the reason to be
searched inside mutt? Are there maybe some other Ideas i can use to
improve my mutt performance?
In any case, if someone else has a ridiculously big mailbox and finds
mutt is slow to open it, consider adding 'unset
maildir_header_cache_verify' to your .muttrc.
Thanks and regards,
David
