sql server clients : Statistics
got the following information, can any one tell me which column and which value I have to check for optimization and fine tunning point of view. Duration CPU Reads Writes 0 0 0 0 0 0 18 0 0 0 0 0 0 0 18 0 0 0 18 0 0 0 0 0 0 0 18 0 10 10 124 0 20 20 128 0 0 0 0 0 Thanks in advance.
Thanks John thanks for your reply but after that value I have to think over
the optimization and index tunning stuff, I mean any bottleneck value. Thanks and have a great weekend.

I mean after what value of I/O and duration I have to think over the
optimization and index tunning stuff, I mean any bottleneck value.

Hi
Duration is the most obvious as this is the length of time (milliseconds) it takes to execute, but then large amounts of I/O may mean poor indexes/code. If you also choose to see the statements within the stored procedure you can pinpoint the statements what that are the worst offenders. You can then start to look at query plans or re-writing them.

Hi
The value will depend on what work is being done therefore you can't really give a definite fixed value. Also if your system may have to meet performance parameters, therefore any query over a certain duration may need to be targetted. If you are looking at impact driven analysis, then you need to look at a cumulative time taken which would target slow running procedures and procedures that are called often. If you have a profile of "normal" activity that is taken over a significant length of time, you can load it into a database table (using the save option in profiler) and pick out the problem areas. You may want to look at the links and investing in the books listed on http://tinyurl.com/476ly For query plans there is some information in Books online, you may also want to purchase "Inside SQL Server 2000" by Kalen Delany ISBN 0-7356-0998-5 John [quoted text, click to view] John wrote:
