I have an unusual problem that I'm trying to diagnose. I have a simple query, SELECT <column1> FROM <table1>, that has just over two million rows. This is used in SSIS package to move the data to a staging database for processing.
The problem is that this table and this table only really crawls. Similiar tables take 20-30 seconds, but this one takes as much as ten minutes. I have ruled out that this is an SSIS issue as I am duplicating the issue in SSMS. I've tried
recreating indexes, limiting the data, checking the state of the PRIMARY store, etc. Nothing seems to help. Any suggestions on what else to check?
