Improving performance beyond what can possibly be reached by using the methods described
below requires purchasing either a Performance Pack or upgrading to PreS Connect (see
Performance Packs). For advice please contact your local sales office (see Objectif Lune's
Contact page).
Engine configuration
As explained in another topic ("Connect: a peek under the hood" on page146) the Connect
Server cooperates with different engines to handle specific tasks.
A DataMapper engine extracts data from a data file.A Merge engine merges the template and
the data to create Email and Weboutput, or to create an intermediary file for Printed output. The
intermediary file is in turn used by a Weaver engine to prepare the Print output.
Configuring these engines to match both the hardware configuration and the typical usage
situation is probably the most effective way to improve Connect's performance.
Particularly launching a higher number of Merge engines can have a great, immediate impact
on performance. When first installed, PlanetPress Connect is configured to use 2 Merge
engines. An engine will run mostly single-threaded. To benefit from modern multi-core systems
it is recommended to run more engines in parallel.
The number of engines is one of the "Scheduling Preferences" that let the Connect Server
manage its workload in such a way that the highest possible output speed is achieved.
For an explanation and guidelines, see "Engine configuration" on page113. See "Scheduling
preferences" on page123 for an overview of the dialogs.
Note
Connect Server and Designer each have their own distinct scheduling preferences. Use the
Connect Server Configuration tool to change Connect Server's settings.
Template optimization
When you find that the speed per Merge engine - the Content Creation speed - is low,
optimizing a template can make a huge difference. For advice on how to optimize a template
see: "Optimizing a template" on page1240.
