Depends on the machine but Bad. that is 30 usec. What kind of machine are 
you running?

I'm running a Soekris net4501.  Some have published articles on the Internet 
saying to the effect that it is one of the most accurate stratum 1 servers a 
person can own without spending a fortune?  I must have a configuration 
problem but I don't know where?
