Initial Testing

Dec 13, 2012

You can do a few simple tests to determine whether the appliance is accelerating your WAN traffic.

To test the installation
  1. Ping the remote appliance at its management address to make sure it is running.
  2. On the Dashboard page, monitor the traffic passing through the appliance. The graphs are updated periodically (by default, once per minute).
  3. Open a connection to an appliance-equipped remote site, using FTP or some other convenient bulk-transfer program such as ssh, rsync, iperf, or wget.
  4. Start a data transfer. Once the transfer starts, the throughput graph should show accelerated bandwidth at the bandwidth limit of either the local or the remote link, whichever is less. The compression usually yields a compression ratio in the range of 1:1 to 10:1, depending on the compressibility of the test file.
  5. Send the file a second time. This transmission should have a compression ratio of at least 100:1, and the throughput should be considerably faster than the WAN link. (If not, you might have reversed apA.1 and apA.2 in your link definitions. You can fixed that on the Configuration: Optimization: Links page. Compression ratios can be read on the Monitoring: Optimization: Connections page (on the Accelerated Connections tab). By default, only open connections are displayed, but if you change the Connection State filter to Any, the data persists for about a minute after the connection closes.
  6. Check for CIFS acceleration. Reboot a convenient PC and mount all the CIFS (Windows) file systems that are normally accessed over the WAN. Doing so should ensure that the PC opens new CIFS connections, which will be accelerated.
  7. Look at the Monitoring: Optimization: Filesystem (CIFS/SMB) page. Your connections to CIFS file servers should be listed under Accelerated CIFS Connections. If they are listed under Non-Accelerated CIFS Connections with “Reason 3: Security Settings,” you need to disable CIFS Signing on your server. See To change the server's setting to allow CIFS acceleration. If the connections are not listed at all, you have a routing or setup problem.
