Difference between cooperative and preemptive explained by Laurent Esnault at 4D Summit 2016

Automatically translated from English

Laurent Esnault, VP of Engineering, explains the difference between cooperative and preemptive processes during his Break Out Session about Preemptive Multi-threading at 4D Summit 2016. Thanks to Preemptive Multi-threading, you can have more parallel processes, and thus add more and more users, either for desktop or for web applications.

If you missed Laurent’s session at 4D Summit 2016, watch this video and enjoy some personal training by the master of preemptive multi-threading!

Web Server in preemptive mode

Automatically translated from English

We are moving forward with 4D v16 on preemptive multi-threading as the 4D Web Server is also becoming preemptive. Just click one checkbox and your application will support more simultaneously connected users, and process more requests in parallel. For requests using a lot of CPU time, execution can be up to 2 times faster!

Preemptive processes for 4D language

Automatically translated from English

Since 4D v11, the database server and SQL server both use preemptive multi-threading. Starting with 4D v13, the Web Server in Static mode also uses preemptive. Now with v15 R5, the 4D language can also be run in preemptive processes.

4D Write Pro commands in preemptive processes

Automatically translated from English

With 4D v16, you can improve your database scalability using the new 4D Write Pro commands in preemptive processes.

If you are doing routines for creating or converting documents programmatically – e.g. invoices … you can now do it with preemptive workers as most 4D Write Pro commands are now thread safe!

XML commands are now thread safe

Automatically translated from English

Want to enhance your database scalability and use all the performance available with your multi-core machines?

With 4D v16, we have extended the list of thread-safe commands in order to use preemptive processes with your code handling XML.
