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.

Now all XML DOM, XML SAX and XML commands are thread safe and can be used in preemptive mode. For example you can have routines on XML references which are twice faster with a quad core machine.

An example database is available to demonstrate the difference between the preemptive and cooperative mode.

A little reminder: all thread safe commands are now marked in doc center with this icon:
