Hi Sasha,
Ok, thank you for the feedback. How Wanos works is by reducing traffic sent between the Core and Edge devices. Reducing the traffic normally translates to a speed increase. In your case you did the test multiple times with FTP. Since the firewall dropped traffic once optimization was enabled it is relatively safe to assume the setup is configured correctly (but there might be something if we look into the detail).
Under the following condition optimization will provide no reduction or acceleration:
- Encrypted traffic (SSL, HTTPS, Signed SMB)
Under the following conditions optimization will provide traffic reduction but not necessarily throughput acceleration:
- Core LAN speed is close to or less than WAN speed or put another way the WAN speed is close to or more than Core LAN speed. e.g. 1 Mbps WAN and 1 Mbps Internet Connection at the Core. Traffic can't transfer faster than the Core LAN network connection. Traffic needs to make it from the source all the way to the destination. If any of the links are lower than the Wanos link being optimized, traffic will be limited to the weakest link. Hence you want to put a Wanos solution over these type of links
- Latency between FTP server and Wanos Core. If the latency is very high between the Core and the FTP server. Remember, only traffic between the Core and the Edge is optimized, so if the file server is far away with a high latency then the link between the FTP server and Core LAN becomes the weakest link. Again the Wanos solution needs to span across the weakest links.
- The speeds being tested is faster than what the hardware can handle
To give you an accurate reason for why you are not seeing acceleration we can look at the following:
Free traffic and lan0 vs wan0 statistics:
1) The results either tell us traffic is being reduced over the WAN or
2) Traffic is not being reduced so we need to go back to the configuration, network layout and protocols to see whats going on
WAN speed, Core - FTP Server network speed and latency between the Core and the FTP server
1) We might find WAN speed is too high for the hardware
2) WAN speed is more or less the same as the Core LAN - FTP Server link
3) Core LAN - FTP Server link is held back by high latency
4) Test with WAN Simulation enabled
