Dave writes "I have a very large table (44 million rows) to which I add about 2.5 million rows each month. After inserting, queries which normally run in about 8 seconds will run slower -- taking up to a minute to complete. After a day or so everything returns to normal.

The table has a couple of non-clusetered indicies (nothing is clustered).

Why does this happen? Would partiioning the table help? Any other suggestions to improve performance?

Thanks!"
