Based on analysis by the Performance Task Force during the Juniper development cycle, these are the recommended maximum file sizes and key configuration settings for Data Import as of the Iris Hotfix 3 and Juniper release. Please work with your systems office or hosting to provider to ensure these configurations are in place. After more performance, reliability, and stability work during Kiwi, these recommendations will be re-evaluated.
