Hi Abishek,


It is not unusual for MarkLogic to respond slower the first time, as it is
trying to put intermediate results in cache to speed up subsequent calls.
But it could also indicate that your approach isn’t as efficient as you
might think. Not sure how many valuation values there are for a single id,
but you are retrieving them all. If there are many, that slows down. Also,
you are calculating separate sum’s for each project id. It should be
possible to pass in all id’s at once to the element-value-query, and get a
sum of the valuation values of all those projects at once. But perhaps you
just want separate sums. In that case: do you need 500 at once? Pagination
might help..



Kind regards,

Geert

*Onderwerp:* [MarkLogic Dev General] Performance Overhead - cts:sum





Hi All,



I am having performance penalty (Average time 23-30 Sec for the first time
and less than 1 sec for next onward hit[which is accecpted]) with cts:sum
over one of the element stores valuation information



-----------------------------------------------------------------------

*for* $id *in* (1 to 500)

return  cts:sum(cts:element-values(

                                xs:QName("valuation"),

                                (),

                               (),

                              cts:and-query((

                                   cts:element-value-query(xs:QName("id"),$
id),

                                   cts:collection-query("/project")

                            ))

                      )

                    )


Do we have any different way to over come performance overhead.
