What is the best Practice to improve MDIS performance in setting up file aggregation and chunk size

Hello Experts,

in our project we have planned to do some parameter change to improve the MDIS performance and want to know the best practice in setting up file aggregation and chunk size when we importing large numbers of small files(one file contains one record and each file size would be 2 to 3KB) through automatic import process,

below is the current setting in production:-

Chunk Size=2000

No. Of Chunks Processed In Parallel=40

file aggregation-5

Records Per Minute processed-37

and we made the below setting in Development system:-

Chunk Size=70000

No. Of Chunks Processed In Parallel=40

file aggregation-25

Records Per Minute processed-111

after making the above changes import process improved but we want to get expert opinion making these changes in production because there is huge number different between what is there in prod and what change we made in Dev.

thanks in advance,

Regards

Ajay

    Hi Ajay,

    The SAP default values are as below

    Chunk Size=50000

    No of Chunks processed in parallel = 5

    File aggregation: Depends largely on the data , if you have one or 2 records being sent at a time then it is better to cluster them together and send it at one shot , instead of sending the one record at a time.

    Records per minute Processed - Same as above
