This was an ASUG webcast last month presented by Greg Sprowles, Kindred Healthcare. Part 1 is here: Customize SAP Design Studio for the Enterprise ASUG Webcast Part 1
Below are my notes.
Replacing Dashboards/XCelsius
Figure 1: Source: Kindred
Figure 1 shows comparisons, with Design Studio has limited controls, rendering is faster than Dashboards and can handle larger volumes of data
XCelsius has more mapping capability.
XCelsius can only render SAP Mobile app (not browser) on tablet – Design Studio can run on browser/SAP Mobile BI app. See caution in red
Design Studio has scripting but much less is needed in Dashboards
Performance
Figure 2: Source: Kindred
You need to figure what user needed; they have over coded a Design Studio application and that decreases performance.
The more graphs and image used will impact performance.
He recommends staying on the latest support packs to improve performance.
See the NOTE in Figure 2 about sequential execution; this will change in 1.5.
Figure 3: Source: Kindred
Figure 3 shows a comparison of the platforms. If use SAP Mobile BI app, you have to use the BI Platform for Design Studio.
NetWeaver performance in their test system is faster than BI platform.
Benchmarking blog shown in Figure 3 compares HANA vs. BIP – 12 seconds on HANA versus 28 seconds to load in BI platform.
Scripts
Figure 4: Source: Kindred
Overall performance will be impacted how you do scripting
Figure 5: Source: Kindred
Figure 5 covers scripting events
On variable initialization – bind value to query variables
On startup – after variable initialization but before background processing
Then load additional data sources in the background
Figure 6: Source: Kindred
An example for startup variable shown in Figure 6 shows populating a list of values in a dropdown box
Sometimes you can’t bind directly to data source so include in startup event
Figure 6 shows populating a dropdown box, set text, and set background processing

The order of execution becomes important too, he said.
Figure 8: Source: Kindred
Global scripts allow you to “externalize” a value, such as a URL – a query string, type
Figure 9: Source: Kindred
Figure 9 shows notes about data sources; they execute serially
You can do things to leverage the same data source
Crosstabs require more data sources than a chart for each layout
In Figure 9 one query feeds the three charts
