We're running top 3.7 on Solaris. On the Solaris 10 systems I've noticed that the "iowait" CPU state never goes above 0.0, even on machines where I suspect there is a lot of disk IO going on (busy database servers). On Solaris 8 it fluctuates (i.e. works) as I'd suspect. The problem seems specific to Solaris 10. I'm not sure on which version top was compiled on, nor with which options.

Is this constant 0.0 iowait on Solaris 10 expected?
