Measuring Latency

[Sean Knox]

Software measurement, as a rule, is unreliable and not accurate. To 
achieve microsecond accuracy (that is also reliably accurate), you will 
need some hardware-based measurement. A company I used to work for (now 
defunct) developed this exact solution. I believe a company called Brix 
was developing a similar product, as was Cisco.

Then again, if can afford to be more lenient with your accuracy, you 
could always use MRTG, cricket, or a variety of other tools to test TCP 
return time at various ports (i.e. 22, 80, 25, etc)
