Special Topic: Performance Considerations

You should first run the SAS Clinical Standards Toolkit validation on a subset of source data to identify general process problems, missing or inconsistent process control metadata, and common (and perhaps correctable) data errors.

You should subset the SAS Clinical Standards Toolkit standard-specific Validation Master data set to remove duplicate checks. For example, CDISC SDTM Janus checks are generally duplicates of WebSDM checks with occasionally different resultseverity values.

You should be toggled off the _cstDebug option, except for when you want to debug specific program errors to avoid exceeding the SAS log-size limitations or to avoid generating large SAS log files.

You should run in batch or using PROC PRINTTO any SAS Clinical Standards Toolkit validation process that involves a large number of checks. This is also true for a SAS Clinical Standards Toolkit validation process that is run with the _cstDebug option toggled on. Doing so avoids exceeding the SAS log-size limitations.
