Downtime was kept to a minimal. New version installed in its own prefix directory and a exim symlink was toggled. exim db emptied. exim restart. Max downtime was 2 minutes. I have gone back and forth between the 2 versions a number of time to be sure and it is just that. 4.73 is noticeably slower.

Didn't help If time permits, I will test other things. I don't like not having the option to use the latest and greatest. Cheers!
