Modifying journaling associated with data mirroring within a storage system

A computer program product for modifying a configuration of a storage system, the computer program product comprising:

• one or more computer readable storage media and program instructions stored on the one or more computer readable storage media, the program instructions readable/executable by one or more computer processors and further comprising:
• program instructions to identify data received at a logical partition (LPAR) of a storage system, wherein a copy program associated with a process for data mirroring executes within the LPAR;
• program instructions to determine a first rate based on analyzing a quantity of data received at the LPAR during the process of data mirroring;
• program instructions to create a journal file from a set of records within the received data;
• program instructions to determine a second rate related to journal files from the LPAR to intermediate storage included in the storage system;
• and
• program instructions to determine to modify a set of configuration information associated with the process of data mirroring by the storage system based, at least in part, on the first rate and the second rate.
