Show output of
top -i
htop
These will show the active processes & how much memory & CPU resource is being used, so read the outputs & see if anything obvious there.
Please describe your Internet connection ie ADSL2+ etc, what upload & download speed is your connection rated at.
You can also test the actual performance eg from a workstation behind the server. Google for a suitable (local to your area) speed test site.

This indicates that you have programmed the wrong FQDN or wrong IP address for your ISP's email server.

It could be due to a dns issue..
I remember that in some occasion, without using a dns forwarder, SME "floods" root servers with dns requests.. in such a case, wan connection becomes useless
