Hello,

I followed these steps in http://wiki2.dovecot.org/MailLocation/LocalDisk

Default to no fsyncing

mail_fsync = never

protocol lda {

Enable fsyncing for LDA

mail_fsync = optimized } protocol lmtp {

Enable fsyncing for LMTP

mail_fsync = optimized }

This gives quite a good performance, but I'm not sure about the risks. Does it mean that things like

*put a Sent Mail to Sent folder *change status of mails

really don't get synced to disk for a long time (hours??). Or do we talk about seconds and everything is fine when dirty pages get synced by the system.

cat /proc/meminfo | grep 'Dirty' lets me assume that there are always just a few KB in the dirty pages and these are written to disk every few seconds. Are the dovecot "mail_fsync = never" transactions inclduded there?

Thanks a lot! Christian
