average output speed.
Likewise, the output speed for an Email or Web template can be found by running it with one
Merge engine and the maximum target speed per job. In the Merge engine's log file, search for
"PPM".
If your jobs are not running at the licensed speed, there may be several ways to improve
performance, as described below. Make sure to address all issues mentioned in this topic
before deciding that you need to invest. Note however that it is not guaranteed that the licensed
speed can be achieved with any job. Creating output for templates with very complex scripts or
complex graphics resources will take a certain amount of time, even on high-end hardware.
Improving performance beyond what can possibly be reached by using the methods described
below requires purchasing either a Performance Pack (see Performance Packs) or upgrading
to PReS Connect. 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127) 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 Web output, 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.
The number of engines is one of the "Parallel Processing 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 to these settings, see "Engine configuration" on page93
and "Parallel Processing preferences" on page103.
Note
Connect Server and Connect Designer each have their own distinct scheduling
