What performance improvement can be achieved for MB5B?

In 2011 SAP has published: MSEG Extension - Redesign MB51/MB5B Performance optimization by Matthias Stegmueller.

This document refers to 5 different SAP notes:

1516684 MKPF fields added to MSEG - Performance optimization
1550000 MB51: Redesign of selection for performance optimization
1558298 MB5B: Redesign of selection to optimize performance
1567602 DB dependent steps to support the redesign of MB51
1598760 FAQ: MSEG Enhancement & Redesign MB51/MB5B

What performance improvement (as a % of runtime for MB5B) can be expected knowing our MSEG database includes about 210.000.000 records and MKPF about 70.000.000 records?

    I have no statistic on MB5B as this transaction is not really used by us, but overall have these notes been the most recognizable performance jump I ever saw and that is only beaten once again by HANA.

    Do not hesitate to implement them.
