bulkinsert

I do Bulk Inserts into a table with about 14 million rows at fiver minute increments during a 7 hour period during the day. These inserts take somewhere between 9-14 secs. However, the first insert always takes about 40 secs. Anyone know what SQL Server 2005 would be doing differently on the first insert into a table for that day?

From what I've read I should probably use the SqlBulkCopy class instead of just using a bulk insert in a stored procedure. Is that that the general consensus?
