MDG Sizing issue regarding to sizing guide

We are implementing MDG project , now we faced performance issue.

Support team give us a Sizing guide, but we still have some question need support to clarify.
Sizing guide for SAP MDG 9.0: https://help.sap.com/doc/6d95f74117f746bdae96763d1c3347fe/SIZING/en-US/Sizing_Guide_MDG_90_v1_3_new....

With the sizing guide provided, we know there is T-shirt sizing model. In Page 10, chapter 3.1 assumption, it descripted reference to in 3.2 as a single process per hour. with “ A change request always contained only one material, supplier or account.”

In chapter 3.2,the table 2 guideline show large category with 1500 process per hour for Material require 16000 SAPs.

Then in Page 11, there is an example: You plan to use Multi-Records Processing for master data governance. Your estimated number of processes shall be 20 per hour and the number of objects 100 per process. Adjust your CPU consumption per object by 0.5 SAPS.20 MDG-M processes * 100 objects * 0.5 SAPS = 1.000 SAPS.
Add the additional required number of SAPS to your already estimated CPU consumption in order to meet the sizing requirements.

We are doubting about the example:
1. If multi-records saps calculation is an additional consumption to T-shirt guideline? Should be added to guideline SAPs like the last sentence of the example? 2. If above question's answer is no, means the example can work independently with the T-shirt table, then we no need refer to the Table

2. just follow the example formula is fine to get a full sizing result?
By the same time, we have more than 460 end users who will process material in MDG, in the end of month/year, will be parallel mass change/creation material business.
So we need more information to check if we need a new sizing.

I am not sure who can support to clarify the Size Guide? Many thanks!

Hi Yuan Li,

you can order a service from SAP to review your performance problems (but I guess it is not free), on my three projects we had performance issues and there was called SAP for investigation - in all three cases the improvement after their recommendation was max 20-30% (but if users have to wait at screen 1.5min or 1.2min they even don't notice the improvement 😉

I assume you are writing about Multi record processing in MDG-M Central Governance, in this case you can forget about CRs with 1000 materials (the default limit in view V_USMD_MC_LIMIT is 100 records and from my experience this is the reasonable max for small materials). For multiple records you should think about Mass Processing in MDG Consolidation (the FIORI applications and MDCIMG config) - however it is "more technical", the workflow is just simple sequential and UI adjustment is limited.
