I am running performance test on a SharePoint site, using HP LoadRunner v8.14. I am capturing perfromance data with the SQL server monitor. One of the counters I am collecting is Probe sacns/sec. The definition of the counter is :Number of probe scans per second that are used to find at most one single qualified row in an index or base table directly. So I am presuming, that if this is high, say over 5000/sec, that this my not be a good thing.... On the other hand it may be better the higher the number is... I have not found any information that indicates one way or the other. If someone could share their around this that would be great. Also If there is somewhere, that not only defines each of the counters but also rates the impact of each that would be great. Most sites I have found do not provide a complete set of defintions.
