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
