I realise that my question isn't strictly 'database' but I know that a lot of DBA's will use the SQLIO tool to check I/O performance on their systems so I'm hoping that somebody here will be able to answer this question:
When I run SQLIO the 3rd line of output says something like:
using system counter for latency timings, 14318180 counts per second
What does that mean? I get different values on different systems, and because I'm comparing different systems I would like to know what that number is telling me (if anything).
