I am running a software vendors utility that updates their schema to make it Unicode compliant. In our test environment a 48GB database completed in 11 hours. I was expecting it to
complete faster on an 8 core, 32GB RAM, Windows 2008 R2 Standard, SQL 2008
Standard server. It appears (from the utility log) I can improve performance by reducing the length of time to run the ALTER TABLE ALTER COLUMN statements. I need metrics to justify additional cores, RAM, Enterprise, etc. What should I be looking at?
