Hi Guru's
We started Archiving in ECC system last week. How can we capture the performance improvement or any way to check the performance improvement before and after archiving?

Start collecting database performance records (before & during archiving).

After archiving project is completed, a database reorg is needed to get full benefits.

Then compare the performance (including backup runtime).

I suggest to measure the runtime of key select commands on the relevant tables. To have some exact data you can check also execution plan and cost estimation.

My personal opinion is that archiving will cause only minor performance increase if the SAP system was properly tuned.

... well ... it is adviced to reorganize the tables after archiving ... so after reorganization you could have measurable performance increase.


PS: please share your experience when the archiving is finished.
