I've found that that question makes the difference between using 6% & 12% ... particularly large data transformations ... but not higher than that. And I've had ample opportunity to test on 2 reporting servers. For one thing, with very large reports one tends to have a lot of I/O binding, which is handled by the kernel. -- -Josh Berkus Aglio Database Solutions San Francisco
