SQL Sasquatch is starting a new series on optimizing disk write to maximize CPU throughput:
When I work with SQL Server batch-controlled workflows, I use the theory “feed the CPUs”. That’s the simplest positive adaptation I could come up with of Kevin Closson’s paradigm “Everything is a CPU problem” 🙂
What I mean by “Feed the CPUs” is that memory and disk response times are primary factors determining the maximum rate for the CPUs to process the data. Nuts & bolts of such a model for SQL Server are slightly different than a similar model for Oracle. SQL Server access to persistent data is always through database cache, while Oracle uses shared access to database cache in SGA and private access to persistent data through direct access in PGA.
