Hey David,

What version of NDT are you running?

Cheers,

When running NDT tests for 10 gigabit connections the client-to-server results
are what we expect, 5+ gigabit/s, but the server-to-client is less than 1
gigabit/s. Can you explain why or how we resolve this. Running NDT tests for
1 gigabit/s connections are consistent in both directions. Below is an
example or our 10 gigabit NDT tests:

running 10s outbound test (client-to-server [C2S]) ..... 5709.95Mb/s
running 10s inbound test (server-to-client [S2C]) ...... 898.46Mb/s

The slowest link in the end-to-end path is a 10 Gbps 10 Gigabit
Ethernet/OC-192 subnet
