Dashboard load time on one of my WPMU installs was taking a real long time to load and causing issues with my php-fpm. The problem was actually the MySql query time.
I had php-fpm on an aggressive kill time of 10s and I revised this to 20s.
I’ve decided to place a redirect to edit.php until I get this mysql query problem sorted. Will probably implement batcache for /wp-admin/ areas.

location /wp-admin/index.php {
rewrite ^/wp-admin/index.php /wp-admin/edit.php permanent;
}
