How many (queue) files are (recursively) in: /var/spool/postfix/{deferred,incoming,active,hold}? The "postfix start" command executs "postfix-script" which runs mostly cheap commands, but also "postsuper -s" to repair the queue directories. If you have millions of queue files on hold or similar, this could take a while. If your queue directory is in NFS or other slow file system, that could compound the issue. -- Viktor.
