I am taking a look at mpstat output and noticed that my smtx (mutex) seems high from what I am use to. In the past when this parameter was above 200 Iwas concerned about my CPU performance. This box has some of those SUN high performance CPUs on it and I am getting mutexs that are consistenting over 3,000. What threashold should you be concerned about for High Performance CPUs?

Thanks
 
I am sorry. I forgot to metion that this is the mutex for 5 seconds.
