Here's the command line I am using:-

imapsync --user1 mark at xxx dot com --password1  PWCHANGED --user2
mark at xxx dot com--password2  PWCHANGED --host1
imap.gmail.com --port1 993 --host2 imap.gmail.com --port2 993  --ssl1 --ssl2
--useheader 'Message-Id' --noauthmd5 --skipsize --folder
'project1/subfolder1/subfolder2'  --regextrans2
's|^project1/subfolder1/subfolder2$|allproject1mail|'

I have also tried adding the following options, but they don't seem to make
any difference to the speed:
--fastio1 --fastio2 --prefix2 'moved' --nofoldersizes --exclude '^project2'
