I forgot two little details: The rest of folders work ok with server side sorting and even threading enabled. However it doesn't thread anything. I see the lists as flat as papers. Second, most of my folders do have several thousands of mails, some of them are of a medium size (all of them under 50mb). The offending folder which causes the bigest problem has the most mails (+23,000 and growing). I had a bigger one with +60,000 files which was slow as hell but otherwise worked fine over a filesystem. So the database might indeed be the issue. -- Jesús Guerrero ------------------------------------------------------------------------------ This SF.net email is sponsored by: SourcForge Community SourceForge wants to tell your story. http://p.sf.net/sfu/sf-spreadtheword ----- squirrelmail-users mailing list Posting guidelines: http://squirrelmail.org/postingguidelines List address: squirrelmail-users@xxxxxxxxxxxxxxxxxxxxx List archives: http://news.gmane.org/gmane.mail.squirrelmail.user List info (subscribe/unsubscribe/change options): https://lists.sourceforge.net/lists/listinfo/squirrelmail-users
