Hi all, I think we found a solution to this. I post it here in case it will be helpful to someone else in future.
There was a missing parameter in the Kannel configuration. Somebody I spoke to talked about increasing the "Windows size" which led the developer working with me to check further and in this post: http://www.nowsms.com/smpp-async-mode he found this discussion where people were discussing why most smscs don't hit above 20mps or on average 10. That led the developer to look more closely at the parameter "max-submit-requests" which seems to default to 10. It seems to set the max limit of messages one can sent before getting a reply. Increasing it has given us 25 mps and above. All's well now. Eugene PS.
