Would be interested to hear why, since I think its an interesting parameter. At least I know of some sun consultants who are the opineon, that this is an important parameter. If I understood the parameter right it should bring you a=20 value, who measures how often (in percentage) the CPU had to wait for I/O operations. Not only disk, additionally network I/O as well (from hearsay) but Im not 100% sure about it. So theoretically it should bring to you a value, if you are I/O bound. Togehter with other values (disk I/O and Network stats it should be easy to see, if you have a problem with your disks or with your network). BTW, are there some automatic tools around for BSD, that=20 automate the process of telling you, where you have problems with your machine or what kernel parameters need an update ??
