Hello Alan, I found the problem and it's not in FreeRadius or MariaDB. I am sorry for this... It's a return-path that is making a problem. In this new structure we have LVS that will make a load balance for our Radius servers behind this LVS. For them to come to my network I have two virtual routers using VRRP for the gateway of those Radius Servers. There is the problem. I powered off on of this VR and now it's running smoothly. Sorry for this inconvenience. I will have to study more about this cluster idea to make it work.

The problem is that for some reason FreeRadius is taking a long time to answer to NAS Access-Request and the NAS send a lot of requests to receive an answer. Bellow I show a FreeRadius log and later I will explain what I saw in this (for the purpose of this log I disabled SQL IPPool and Simultaneous-Check):
How long does it take to respond? The debug log you posted doesn't show times.
And the server can easily process 10K packets/s in the default configuration. if it's slower for you, then you changed something locally which slows it down.
Also, the NAS retransmits don't necessarily mean that the server is slow. Maybe the NAS isn't getting the responses, or the NAS is broken.
