Fellow Techies--
We're migrating an ETL process from a hardware environment with about 240 GB of installed memory to one with 1.5 TB for physical memory, 1.5 TB of virtual memory. This will be the "maiden voyage" on this new box. On the old box, the process took roughly 5 days to process from start to finish, with the longest part of the process surrounding multiple sets of MERGE statements against very large data sets. In calculating what we can expect for performance on the new hardware, what should I be looking at?
