High number of reads in SQL Profiler

Question

I am looking at some performance turning of my queries, and notice that Query Profiler is showing a HIGH number of reads, but low durations.

Is that an accumalation of reads? It seems to increase all the time - but the query it's self, seems quick, as far as 'duration' goes.

Is this something to worry about?

Answer 1

HIGH number of reads, but low durations.

This can be a sign of execution plans which use parallelism. You may look, also, at CPU vs. Duration. If CPU is greater than Duration then this hypothesis is true.

It seems to increase all the time

Increasing value of Reads (logical reads)

Maybe, another concurrent connection insert data.
