Sure. Beating your ETL/Replication performance into shape is always beneficial. On our Salesforce side, we have a process that replicates one sObject which takes 5 hours each night, pulling over 400 custom fields. We can only run it once a week, it takes so long. The SF team won't spend a few minutes trying to pare the list down to essentials. With our NetSuite replications, I started with a minimalist approach. If we need a new column on a record type, we can add it, but someone has to justify the additional data with a real business or use case. As a result, our entire NS replication task runs in less than 2 minutes.
