hello all,
I had been thinking/researching for a while but not find an perfect way, so please help.
To show the result of how much SQL Server performance would be monitored/improved/tuned that we will spend a lot effort on, a matrix of indicators to measure it would be very helpful to show with data. It is SQL 2012 AlwaysOn and on Windows server managed by System Center. How did you present that SQL Server and the DB are improved on performance in the past? I did not think TPCx fit here, and did not think perfmon fit(we need a simple way to tell like: today the perf is like this, then after our work, the perf now is increased by 100%, and aggregate the perfmon counters are complex to present and show); I used to think that maybe sum/avg per execution time of top 20% time consuming and frequent (and how frequent?) queries, but after those are tuned, new ones will stand up. And I don't think bad index/missing index are good here to measure as it is not result oriented. (it is easy to show perf improved for several specific queries, but how about a SQL instance or DB?)
currently the top queries would take 30 to 200 seconds to execute.
Could you share how did you measure the SQL Server performance is improved?
thank you very much
Dannol
