Running a job as fast as possible
Number of parallel engines per Print job
Two or more engines of a kind can be combined to work on the same Print job. Generally jobs
will run faster with more than one engine, because sharing the workload saves time.
However, running one job with multiple engines reduces the number of jobs that can be
handled at the same time by that kind of engine, because there are only so many engines (and
speed units) available.
To select a number of parallel engines per Print job size:
1.
Select Window > Preferences... from the menu.
2.
Under Scheduling, select Merge Engine.
3.
Set the Parallel engines per job for medium and large Print jobs; small jobs always get
one engine. You cannot assign more engines than the total number of engines launched.

Click OK or Apply.
Note
When each individual record in a job is composed of a very large number of pages, the
Memory per engine setting and the machine's hard drive speed are probably more
important than the number of Merge engines, since one record cannot be split over
multiple cores (see "Memory per engine" on page118).
Number of speed units per Print job
If a Print job of a specific size has more than one parallel speed unit assigned to it, that
multiplies its speed, however it reduces the number of Print jobs that can be run
simultaneously.
When no other Print output operations run at the same time, a single job will get all available
speed units, or the maximum number of speed units reserved for jobs of that size (see "Dividing
processing power over jobs" on the next page).
