You can do a few
simple tests to determine whether the appliance is accelerating your WAN
traffic.
- To test the
installation
-
- Ping the remote appliance
at its management address to make sure it is running.
- On the
Dashboard page, monitor the traffic passing through
the appliance. The graphs are updated periodically (by default, once per
minute).
- 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.
- 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.
- 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.
- 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.
- 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.
