cores, Windows Task Manager will show 4 cores and 8 logical processors on its performance
tab. On a CPU like this, 5 or 6 engines can be configured to run in parallel.
To configure the number of engines:
1. Open the Connect Server Configuration utility tool (see "Server Configuration Settings"
on page90).
2. Under Parallel Processing, go to the Content Creation tab and set the number of Merge
engines for the various tasks.
3. Go to the Output Creation tab and set the Reserved Weaver (Output) engines.
See "Deciding how many engines of each type to launch" below.
4. Click Apply or Apply and Close.
It is advised that you do not configure more engines than can be backed by actual processing
power. This adds overhead while not adding processing power.
Deciding how many engines of each type to launch
When jobs run in parallel, different types of engines may run at the same time. It depends on
the usage situation which type of engines has the biggest impact on performance.
The more and the larger operations of a kind need to be performed simultaneously with smaller
operations, the sooner you will see a performance increase when using multiple engines.
Merge engine
Generally, launching a relatively high number of Merge engines results in better performance,
as Merge engines are involved in the creation of output of all kinds (Print, Email and Web) and
because content creation is relatively time-consuming.
DataMapper engine
Adding DataMapper engines might be useful in the following circumstances:
l When large data mapping operations have to be run simultaneously for many jobs.
l When frequently using PDF or XML based input. Particularly in the case of XML input
with large individual records.
l When the All In One plugin is used often in Workflow configurations and there are more
than two Merge engines running.
