Try the c client to see if the problem is at the client or server end.

Dear members:

I thought I would try again to find an answer to this since I noticed recent messages related to NDT on 10 gig devices:

I have tried several approaches to use NDT on a server with a 10 gigabit
interface.  I wonder if there are any limitations on the server to client
tests using either web100clt or the Java client.  I have not been able to get more than around 2.6 gigs
server-to-client.  The client-to-server test can go over 9 gigs even without
extensive tuning.  On the same server, I can get over 9 gigs in each direction
to a neighbor server using iperf tests.

Are there any tips on running NDT on a 10gig capable server?

Thanks,
Nat Stoddard
