I was using 1.182 due to the internal dates not syncing. I found that it would hang a long time on large emails. I did an strace on the process and it was doing lots of mremap'ing.

I checked for a new imapsync and found this in the changelog

revision 1.213
date: 2007/02/16 04:07:19; author: gilles; state: Exp; lines: +168 -11
- Back to append_file() modified -> append_file2()

I tested 1.213 with no additional patches and it synced the dates just fine. I haven't done much comparison yet, but it seemed faster. Here's my command:

time ./imapsync.1.213 \
    --ssl1 --authmech1 PLAIN --host1 $HOST_FROM --user1 "${USER}${DOVECOT_MASTER}" --passfile1 $PWORD \
    --exclude '^UCD-spam-\d\d' \
    --ssl2 --authmech2 PLAIN --host2 $HOST_TO   --user2 $USER --passfile2 $PWORD \
    --regextrans2 's/UCD-spam/Junk/' \
    --syncinternaldates \
    1>&2 >> $LOG
