Hi everybody. Thank you very much for your help. The situation now is:
1- As my /home folder is ecrypt I added to my .muttrc your suggestion (folder-hook 'archive' 'push <toggle-write>; unset maildir_header_cache_verify') Apparently, after a first refresh, the update of files looks inmediate, but after using mutt a little bit, it turns slower againg. The end result is that there's not a significant improve in performance: Sometimes it is very fast, sometimes it is very slow. 2- I checked my data, ang got this: jm@jm-ThinkPad-X200s:~/.mail/GMail/[Gmail].All Mail$ du -h 4,0K ./tmp 940K ./new 9,4G ./cur 9,4G . jm@jm-ThinkPad-X200s:~/.mail/GMail/[Gmail].All Mail$ find . -type f | wc -l 47860 The data shown in my mutt status page is the same (I am using google apps, premium, so nothing strange about having more than 7Gb) 3- My system is 32 bit. jm@jm-ThinkPad-X200s:~$ uname -m i686 4- After working a little bit with I/O, I get: TID PRIO USER DISK READ DISK WRITE SWAPIN IO COMMAND 120 4886 be/4 jm 2.38 M/s 0.00 B/s 0.00 % 96.43 % mutt Honestly speaking, I don't know what to do with this information. Thanks again for your help. jm PS: will keep tokyo-cabinet for later, thanks. Think that understanding what is happenings is neccessary first.
