how to test transfer network speed

[mrmustarde]

Forgive my ignorance, but I am looking for a good quantifier method for testing the speed of my afp. I downloaded Xbench and this offers great detail with respect to local drives and shows great results when run on the server, but I am looking for something similar to this for network shares from the client angle. If you can help, it would be greatly apprecieated. Thanks.

The Server Admin app included with OS X Server has some generic graphing that can give you an idea of how it’s running.

If you’re running an Xserve then the Server Monitor app can give you a graph of packets or Kbits in or out of each interface.

There are other, more detailed/accurate, apps available but these are graphical and “free” if you’re running an Xserve & OS X Server.

iperf is good for testing raw network speed. It uses a client/server architecture and can do multiple connections.

To check AFP specifically, you can do:

client –> server
——————–
dd bs=1m count=1000 if=/dev/zero of=/Volumes/mounted_volume_name

server –> client
———————
dd bs=1m count=1000 if=/Volumes/mounted_volume_name/file_name of=/dev/null

This will take your client disk performance out of the equation
