 ### Handling Reduce Your Request Rate Errors
 
-On operations that require a checksum calculation to an S3 object at rest, iRODS must read the object's data to calculate the checksum. The default buffer size for these reads is 1 MiB. Each of these read requests map to a separate GetObject request to S3 with a range of bytes. This can exceed the request rate that the S3 provider allows.

+To resolve this problem, the read buffer size can be increased by updating the `checksum_read_buffer_size_in_bytes` value in the `advanced_settings` stanza of server_config.json. This change should be made for all servers that can serve requests to that S3 resource.
 
 The following is an example of increasing this buffer size to 10 MiB:
