Tuning: DB Server
Tuning: Excessive Server Calls
Technique #1: partitioning transactions via stored procedures
Technique #2: partitioning non-visual logic via NVOs
Technique #3: eliminating recursive Embedded SQL
Technique #4: grouping multiple server calls with Appeon Labels
Tuning: Heavy Client
Technique #1: thin-out “heavy” Windows
Technique #2: thin-out “heavy” UI logic
Manipulating the UI in loops
Triggering events repeatedly
Performing single repetitive tasks
Initializing “heavy” tabs
Using ShareData or RowsCopy/RowsMove for data synchronization
Using computed fields
Using DataWindow expressions
Using complex filters
Using RowsFocusChanging/RowsFocusChanged events
Technique #3: offload “heavy” non-visual logic
Tuning: Large Data Transmissions
Technique #1: retrieving data incrementally
For Oracle database server
For all other database servers
Technique #2: minimizing excessive number of columns
