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 :
[ptnId15]>=RangePartitionNew(@myvar,(1),date1,date2,….
[ptnId15]<RangePartitionNew(@MyOtherVar,(1),date1,…
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 ?
