NimbostratusBIG-IP Virtual Ed. Capped at 115mbits Via Iperf Tests
AWS Marketplace instance: F5 BIG-IP Virtual Edition 1Gbps Best
Hello,
We're seeing an oddity in speed when running the virtual edition(c3.8xlarge).
Using iperf to the F5 instance direc...
My first guess is that the traffic distribution through the tunnel is not optimal. 115mbps will workout as 225mbps bi-directional, and if your instance has 4 tmms, then this may line up with why you observe 1000mbps when you connect directly (225 x 4 ~= 900). That is just an educated guess, but that is a very possible cause of the bottleneck:
all the traffic is hitting only one TMM and that TMM gets maxed out (it is tied to a single CPU core) and you can't go faster than that.
