 - **Use large files for import**. The file size of a single `import` operation should be more than 200 MB. Smaller files might result in slower import times.
 
-- **Import FHIR resource files as a single batch**. For optimal performance, import all the FHIR resource files that you want to ingest in the FHIR server in one `import` operation. Importing all the files in one operation reduces the overhead of creating and managing multiple import jobs.
+- **Import FHIR resource files as a single batch**. For optimal performance, import all the FHIR resource files that you want to ingest in the FHIR server in one `import` operation. Importing all the files in one operation reduces the overhead of creating and managing multiple import jobs. The combined total size of all the files in a single import should be greater than 100 GB or 100 M resources. 
 
 - **Limit the number of parallel import jobs**. You can run multiple `import` jobs at the same time, but running multiple jobs might affect the overall throughput of the `import` operation. The FHIR server can handle up to five parallel `import` jobs. If you exceed this limit, the FHIR server might throttle or reject your requests.
