Feedback
After one and a half year
Your application is
awesome
but it is so slow
23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 7
We started performance optimization
1. Define performance goals from the customer perspective
2. Measure performance goals in different set ups
3. Tweak as long as the performance goals are not met
Rule of thumb doubling performance means 10% - 30% more effort. Sometimes you
have to be 8 times faster which means 3*10% - 30% ~ 60% more development effort

Standard techniques for performance improvement UI5
23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 10
– Use Chrome
– Reduce amount of HTTP requests
▪ Bundle controllers, controls and view as Component-preload.js
▪ Use batch for ODataModel
▪ Use client mode for ODataModel binding
▪ Use OpenUI5 from a CDN and hope it is already cached
– Reduce size of HTTP requests
▪ Compress HTTP requests
▪ Use HTTP2
– Parallize HTTP requests
▪ Use sap.ui.define (AMD) syntax
Advanced techniques
23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 11
– Optimize rendering by disabling invalidation and updating DOM
– Using virtual lists by just rendering the elements shown in the viewpost
– Using canvas for rendering objects (openlayers)
– Use webpack to only bundle the JavaScript that is needed
– Use new Chrome Developer Tools to find the code that is really executed (coverage)
– Use new support assistent to analyze runtime behavior
– Send samples of live application to monitoring database

Optimizing an SAP Fiori Application Based on a Real World Example

  • 1. Optimizing an SAP Fiori Application Based on a Real World Example Session ID: DX301 Manuel Blechschmidt, FarmFacts GmbH, SAP Community Network 25. - 29.9.2017 SAP TechEd Las Vegas
  • 2. 23.07.17FarmFacts GmbH, Abteilung, Verfasser Seite 2 Please build the best digital farming platform on earth
  • 5. OpenUI5 Client & Openlayers 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 5
  • 6. Development cycle In the first year we did this weekly 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 6 Develop Release Analyze Feedback
  • 7. After one and a half year Your application is awesome but it is so slow 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 7
  • 8. We started performance optimization 1. Define performance goals from the customer perspective 2. Measure performance goals in different set ups 3. Tweak as long as the performance goals are not met Rule of thumb doubling performance means 10% - 30% more effort. Sometimes you have to be 8 times faster which means 3*10% - 30% ~ 60% more development effort 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 8
  • 10. Standard techniques for performance improvement UI5 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 10 – Use Chrome – Reduce amount of HTTP requests ▪ Bundle controllers, controls and view as Component-preload.js ▪ Use batch for ODataModel ▪ Use client mode for ODataModel binding ▪ Use OpenUI5 from a CDN and hope it is already cached – Reduce size of HTTP requests ▪ Compress HTTP requests ▪ Use HTTP2 – Parallize HTTP requests ▪ Use sap.ui.define (AMD) syntax
  • 11. Advanced techniques 23.07.17FarmFacts GmbH, Manuel Blechschmidt Seite 11 – Optimize rendering by disabling invalidation and updating DOM – Using virtual lists by just rendering the elements shown in the viewpost – Using canvas for rendering objects (openlayers) – Use webpack to only bundle the JavaScript that is needed – Use new Chrome Developer Tools to find the code that is really executed (coverage) – Use new support assistent to analyze runtime behavior – Send samples of live application to monitoring database
