+====== Fertigungsmodul Performance ======
+===== Problem Description =====
+Find out what is the root of the problems with "Fertigungsmodul".
+  * **-** Ask Torsten which problems they have
+  * **-** How is it possible to see these problems?
+  * JProfiler is under "C:\Program Files\jprofiler13"
+  * Menu
+    * Fertigung
+      * Leitstand
+        * Fertigungsauftrag
+          * Netzplan (Über Menü? Kontextmenü?)
+            * Endprodukt
+            * Zwischenprodukte
+  * Produktionsplanung
+  * Beispiel-Matnum:
+    * .740 (und dann Pfeil-nach-unten drücken)
+      * FB-Nr. 00126472
+    * 1216
+  * Groovy Klassen:
+    * SvBoPrdNet
+    * SvBoPrdNetImpl
+      * setBoPrdNetPrdDocQuantityAndReloadSuc()
+    * SvBoPrdNetImplBase
+    * FrBoPrdNet
+      * ''handleElementDataChanged()''
+        * :946 => ''busObj = svBoPrdNet.setBoPrdNetPrdDocQuantityAndReloadSuc(busObj, boPrdNetPrdDoc, (EFCQuantity) oldval, (EFCQuantity) newval)''
+  * ''EFCThreadUtil.doLater()''
+    * -> wird zu oft aufgerufen?
+    * auf die Methode wird gewartet
+      * Torsten meint so soll es auch sein, da es in einem AWT-Thread passiert/passieren soll
+===== Found facts =====
+  * JDBC calls take relatively long time:
+    * the first 10 calls need the most time
+      * ca. 8 seconds with my scenario on the local DB srv07
+      * ca. 3 minutes on the Zimmer Test-DB, if I move 5-7 entries on the screen "Leitstand Bereich VP"
+===== Profilers =====
+  * [[https://www.ej-technologies.com/products/jprofiler/overview.html|JProfiler]]
+    * [[https://www.ej-technologies.com/resources/jprofiler/help/doc/main/introduction.html|JProfiler Help]]
+    * [[https://www.ej-technologies.com/resources/jprofiler/help/doc/JProfiler.pdf|The definitive giude to JProfiler]] (PDF)
+  * [[https://visualvm.github.io/|VisualVM]]
+===== TOP-Selects =====
+==== select 1 ====
+  * Ursache
+    * ''MdMatMrpBrrRepositoryImpl.getBoFromDb()''
+      * ''getForObj()''
+        * ''...''
+===== Misc =====
+  * to debug html page "graph.html" in Chrome:
+    * add the manual call of ''setData()''
+      * in ''graph.html'' add the line to the bottom of JavaScript code
+        * ''setData(...)''
+          * where ''...'' is the JSON code copied from ''GraphView.fillGraph()'' during debugging
+    * find out the URL of "graph.html"
+      * see ''GraphView.getGraphURL()''
+    * call this URL in Chrome
+  * Maybe we can do something better if we write a better version of ''DcBomDocCompactRepositoryImpl.getMatnumMdBomDoc()'' which uses own "select" statement to select only one record from DB, instead of: <code>...
+db = getDao(company, bomdockey, bomdocnum)
+if (db != null) {
+  return new EFCMatNum(db.bommatnum)
+}
+...
+</code>
