I have that kind of behavior from my server, but in this case I don't know how I can solve this... I have a very big partitionned table, the seek gives me Something like :



the information shows me that it uses a partition range from (in my case) 5 partitions

Then I have a predicate with the field >= @Myvar and field < @Myothervar

this gives me a residual IO... 1.200 Million read for 990K rows...

Any idea on this ?
