4D Server v11 SQL Scalability test

How many simultaneous, active clients can 4D Server handle? This laboratory scalability test examines the limits of a real application on 4D Server v11 SQL.

 

Since the recent announcements about scalability in 4D v11 SQL Release 3, especially in regards to those helped by improved management of multi-processor operations, many people have had questions about the number of simultaneous clients that can connect to 4D Server.

 

4D v11 SQL in a Real Application

4D v11 SQL performance tests under real-world conditions.

 

Is the whole greater than the sum of its parts?

 

This is the question we had in mind when creating some of the new algorithms in 4D v11 SQL. Although every command has received individual attention, and while we know how to assess their improvements through unit tests, it’s the perception of the user that determines the total improvement in performance.

 

4D for OCI

Communicate natively with Oracle using the Oracle Call Interface (OCI).

4D View

An advanced spreadsheet integrated into 4D that can be entirely controlled via the 4D language.

4D Write

Powerful word processing tools integrated right inside of 4D.

Data Client

4D Client is optimized to reduce network traffic. As of 4D v11 SQL, only modified data is sent across the network.

SQL Server

Query any SQL database via a native ODBC Driver using 4D's integrated SQL server.

Web Services Client

Easily call on Web Services using 4D as a Web Services Client.

Server-side Code Execution

The method parameter "Execute on server" allows a method to be executed on the server, considerably reducing the number of requests exchanged with the client.

Remote Administration

Reach your admin window remotely, or open it for your users using the OPEN ADMIN WINDOW command. Restart your servers remotely. (After compacting, for example.)
