May be I am not able to explain.. Let me elaborate the scenario.
I have a LAB setup as shown below:
LAN -> WANOS (HQ) -> Router <-> Router ->WANOS (Branch) -> LAN
I ran 4 test cases.
1. FTP traffic, LAN to LAN, WANOS at both ends, Throughput 10 Mbps
2. FTP traffic, LAN to LAN, remove WANOS from Branch, Throughput 1Mbps
3. FTP traffic, LAN to LAN, remove WANOS from HQ also, Throughput 100 Mbps
4. HTTP traffic, LAN to LAN, WANOS at both ends, Throughput 1 Mbps
As per my understanding, WANOS v3 is of express license, so throughput will decrease to 1/10 i.e 10 Mbps, which is working fine. But as soon as I remove WANOS device from Branch, throughput drops to 1 Mbps. It should not drop.
Similarly, with HTTP traffic, throughput in first run is 10 Mbps, but if we download same file again, it drops to 1 Mbps.
