We think we've probably hit our bottleneck until you can enable dccp -
the two cacti plots attached are the connections to our stack with most
of the worker nodes attached and as you can see we're basically maxing
them both out now.
Interestingly the outbound traffic of ~1Gb/s is probably data being sent
from the storage on the Worker Node stack to be retransmitted back from
a GridFTP door on the other stack. The switch to dccp should essentially
double our throughput.
I'm currently buying the parts to up the link to 10Gb/s, it'll be
interesting to run the test again once that's in place.
Yours,
Chris.
