Performance#

Areas of possible problems#

1. Browser rendering
2. Network bandwidth
3. Server side
   • slow ABAP code
   • strange business logic
   • memory consuption
   • too many contexts or too big
   • inefficient SQL

WDA Performance Tools 1-6#

(1) Performance Monitor#

sap-wd-perfMonitor=X	URL parameter
Shift+Ctrl+Alt+p	Start shortcut

• a little bar upper right will appear
• Memory = SAP session memory on server
• ">>" shows more information

(2) Browser Debugging Tools#

Note: IE Addon "HTTP Watch" is not necessary anymore as every modern browser provides analysis tools under F12.

• All browsers provide debugging tools with F12
• In Firefox "Firebug" can be used alternatively
• Fiddler (for IE) is even more detailed

(3) x.STAD - SAP Workload: Business Transaction Analysis #

• to analyse server side problems
• no activation necessary
• drill in shows breakdown more detailed (see database activity)

(4) x.ST05 - SQL Trace#

• if the database causes problems
• need to be activated before

(5) Runtime Analysis#

• if code causes problems
• In x.SAT you can create settings/filters to be used as variant later !
• Runtime diagramm in x.SAT possible

1. x.SE80 > "Repository Info System" > Web Dynpro > Web Dynpor Applicat.
2. Enter application name > Execute > Pick it and open it
3. Menu > Goto > HTTP Service Maintenance
4. Mark service
5. Menu > Edit > Runtime Analysis > Activate
6. Execute any web dynpro application in browser
7. (SICF) Menu > Edit > Runtime Analysis > Deactivate
8. x.SAT > Evaluate

x.SICF => Authorization Profile, Debugging, Trace?

(6) Memory Inspector#

• memory snapshots allows to analyse memory growth/diffs

1. Take snapshots via Performance Monitor > Unfold > Memory > "Write Memory Snapshot"
   or: Debugger > Special Tools > Memory Analysis AND Services Tools > Take Memory snapshot
2. Menu > System > Utilities > Memory Analysis > Compare Memory Snapshots (x.S_MEMORY_INSPECTOR)
3. Get delta between two snapshots with the "Memory Snapshot" Dropdown list (t_1 - t_0), (+)red, (-)blue, (o)black

WD_TRACE_TOOL#

x.WD_TRACE_TOOL (RAT Trace/ Runtime Analysis Tool)

3. Enter component name
4. Execute
