With simple and straightforward PowerBuilder coding, you can tune the performance of your application to have excellent performance over the Internet. No new skills are required. Tuning is performed using standard PowerBuilder programming in the familiar PowerBuilder IDE. Plus, Appeon equips you with tools that assist you through every step of the performance tuning process.

What tools will I use to performance tune my application?
- Performance Tuning Guide
- Heavy Windows Report
- Runtime Tracing Report

What is the Appeon Performance Tuning Guide and how will it help me improve my applications performance?
The guide helps developers understand the expected performance of the application and how to improve its runtime performance. It outlines the performance tuning process, highlights common problems and solutions, and provides a detailed list of PowerBuilder features that can slow-down performance.

What features of Appeon Developer will help me in the performance tuning process?
The Heavy Windows Report lists all windows that will perform that are "heavy" with data-intensive controls (e.g. DataWindows). This helps you to quickly identify areas of the application that may need optimization.

How can I see what parts of a window are affecting performance?
Using the Runtime Tracing Report you can pin-point exactly what processes are slowing down a window.

• Work around a vast number of unsupported features by implementing them in Appeon Server NVO components and calling these NVOs from the PowerBuilder client. In general, most unsupported features that are non-visual in nature, such as external function calls can be worked around in this way.
• Enhance Web runtime performance by moving PowerBuilder business logic into NVOs that run in a fast C++ environment on Appeon Server.
• Use an n-Tier NVO as a bridge to call other NVO components and/or C++ components in BEA WebLogic/IBM WebSphere or other application servers from Appeon Web applications.

Appeon 5.0 supports both single and double-byte character sets for text in the user interface of the application and the application data (e.g. data retrieved from the database). It has been tested and certified for English, Simplified Chinese, Traditional Chinese, Korean, and Japanese. However, Appeon 5.0 has not been certified or tested for other languages, such as Spanish. As such, you may encounter language issues when working with a non-certified language.

Appeon is committed to resolving language issues for non-certified languages, if Appeon is able to reproduce the issue in-house. Therefore, customers using non-certified languages who encounter language issues will have the opportunity to work closely with Appeon so that their issues get resolved. Currently, there are a number of customers around the world using Appeon with non-certified languages, including Mexico, Peru, France, Italy, Greece, and Russia.
