This is very old tread, but had been actual for me (currently using
kannel 1.4.5, tried also on kannel 1.5.0 development version).
No parameter change suggested not taking any effect on this issue and
you will get consistent 1 msg/sec unless you change your config.
I am using mysql for saving messages and delivery reports in DB and many
opensmppbox connections (more than 20) which I am using for incoming MT
traffic.
So the problem resolution lies in configuration model.
When opensmppbox receives message there is no need to store dlr in
database, and this is also concern to bearerbox when it sent message to
smsc.
Just set dlr-storage = internal(which is default) for both opensmppbox
and bearerbox and leave sqlbox to store your messages to DB.
Finally take into consideration that this configuration requires
reliable hardware and you should avoid to restart kannel in case you
have any live traffic.
Below is configuration which is working like charm.
