In one of our application, we need to update huge dataset (aprox. 10 Million rows) with multiple columns. We do not have too many indexes on the table and we don't use Transaction (it may not look right, but we really don't need Transaction). On a good hardware (4 CPU, 4 GB RAM) it takes aprox. 10-15 hrs to complete the operation. Are there any ways to reduce this time by half? Thanks for help.
