You probably got your measurements wrong somewhere, or you're reading
them wrong. I presume you're routing 253 Kpps, and not 253380 Kpps, you
should probably read the "." as a decimal floating point, with the .380
being 380 pps, NOT 380 Kpps
If you would be receiving 253380 Kpps, and...

...only pushing 1.7 Gbps of bandwidth, I'd say you're the first NSP with
an average package size of approx. 7 bits (less than a byte per packet
seems hardly likely)

1.7 Gbps should not choke an M40 in a set-up like this, and 253 Kpps is
not an unusual high amount of packets. I suggest you start
troubleshooting your network or your config, or perhaps check if any
hardware might be broken.
