Release 10.1A: OpenEdge Application Server:
Developing AppServer Applications

Compiled compared to precompiled code

The execution process for noncompiled code on an AppServer is identical to the process for regular runtime compiled code on a Progress 4GL client. Standard Progress 4GL compilation processing activities and behaviors occur. Therefore, when noncompiled code must be used, from a performance perspective, there is the possibility of some improvement gains when the AppServer is running on a more powerful machine than the client application.

For example, if the AppServer you are running is on a faster machine, then the compilation process might occur faster for code compiled on it. Also, if AppServer agents have a self-service connection to the database, then compile-time schema information will not have to be sent over the network.
