Analyzing Throughput Testing Data

After experimenting with some of the Smartbits configuration parameters, we discovered that there was no packet loss at any throughput load of 4% or less. Still not totally conclusive, but it hinted that the learning process was not a problem. We did consider that at 4% load, the firewall could be buffering the first packet and that the learning could have happened before the second packet arrived.

At that point, the firewall vendor engineer who was working in the lab mentioned that the firewall was stateful and that its state timer for UDP was 60 seconds.
