That is not necessarily true either. It will depend on how much idle 
bandwidth you have after 20 outbound streams are active. My guess would be 
- not much.

If you generate enough email to saturate your outbound bandwidth for 40
minutes then it doesn't matter how many parallel streams you divide it
into, you cannot deliver it in less than 40 minutes.

But in any case, as DJB says - don't speculate - profile.
