AgendaNew performance features in R2 and R3How to prevent performance problemsCase study of a recent load test

How to troubleshoot performance problemsEnd to end tuning explained on a real sampleCode optimization patterns explained based on reports

Improvements

Performance Improvements in R2 and R3• Retail• Service industries• Supply Chain

Management

• Global Financial Management

• Foundation• Life Cycle Services

• Parameter sniffing • Reports

Performance features in R3

What is parameter sniffing?Why not trace flag 4136?What is the alternative• Query tuning• Plan guide• ForceLiterals

Any save alternative on global level?• From Microsoft Dynamics AX 2012 R2 CU6 onwards• UPDATE SYSGLOBALCONFIGURATION SET [VALUE] = 1 WHERE NAME IN

( 'DATAAREAIDLITERAL', 'PARTITIONLITERAL')• Restart AOS

Parameter sniffing

Sample query with setting offSELECT TOP 1 T1.SALESID,.......,T1.RECIDFROM SALESTABLE T1WHERE (((PARTITION=?)      AND (DATAAREAID=?))      AND (SALESID=?))

Sample with setting onSELECT TOP 1 T1.SALESID,.......,T1.RECIDFROM SALESTABLE T1WHERE (((PARTITION=5637144576)      AND (DATAAREAID=N'ceu'))      AND (SALESID=?))

Parameter sniffing

Reports Development – Things to look for

Reports Performance

Case Frequency Freshness Concurrence Contention expectation Solution

1 Transactional, simple Real time High High No high Query

2 Transactional, process Real time High High process High RDP

3 Transactional, high volume Real time High High Process, input very high Query, RDP, Static RDCE,

4 Fixed period, kpi < daily given High No high Cube,

5 long running report As needed low Low process Low PreRDP

6 mixed long running Random High Medium High Mixed split PreRDP/RDP

Reports Development – Things to avoid• Don’t use fetch method to process line by line in RDP• Don’t use RDP unless Query based report can’t do to work• Don’t assume pre-processed RDP is faster for concurrent user reports

Scenarios

Recent POC based on usage profile

Scenario DescriptionPost Trade agreements to stores Send trade agreements to retail stores for 30,000

products 

Assortment publishing to stores Publish product assortments for 30,000 products including converting pre-actions to action 

Trickle feed from the stores Trickle feed all transactions from the storesInventory reservation and statement calculation First part of the end of day processing

Statement posting Second part of the end of day processing

Goals• Number of POS stores: 1300• Number of tills per store: 5• Number of transactions per POSper day: 240 with 1, 5 and 15 lines• Number of Products: 30,000• Data generated for the test: 6 months• All scenarios need to complete within a 10 hour time frame• Workload of the trickle feed and EOD scenario increased 2 times by 25 %.
