Hi  Susan Coulter

Very thanks for your reply

Very interesting and especially for perfmon. How I understand the 
perfmon can dump all counters very fast (i hope it more fast then dump 
it in cycle one by one). Thanks for this info.

But nevertheless, can your or somebody explain how to use sampling 
control mechanism for perfquery ?

/"//perfqery //-c, --smplctl////show port samples control"

/in this mode, I would like to collect all available counters of the IB 
port with time stamp provided by "tick" counter from the device.

The time stamp form tick counter will allows not depending on time from 
host which collect counters from IB port .

Sorry I am noobe in maillist
