xdelay is the how long the delivery attempt took. It depends primarily
on network latency and the speed of the remote SMTP server. If the
increase you're seeing is caused by raising concurrencies or incoming
sessions, it's probably due to either saturating your network link or
overwhelming remote servers. It could, however, be unrelated to the
changes you made.

Your explanation sounds likely.
