Determining The Single-Server Throughput For A Solution - Lexmark C792 Manual

Testing and deploying workflow solutions
Determining the single‑server throughput for a solution
When building or upgrading an LDD system around a particular solution, the single‑server throughput of the solution
should be determined to help in sizing the system. You can determine this value by testing the solution with the
performance simulator.
For more information about system sizing using the value determined by this process, see the Lexmark Document
Distributor Administrator's Guide.
Note: This test should be performed either on a separate test LDD system with at least one server matching the
performance of your production system, or during a time that your production system is not processing any other
jobs.
1
On the LDD system where the solution is being tested, set all but one server offline.
Note: If unequal servers are in the system, then you may need to test the solution on each server for the most
accuracy.
2
In Eclipse, click LDD SDK > MFP > Performance Simulator.
If you have not installed the MFP emulator and performance simulator, then follow the instructions on the computer
screen.
3
From the MFP Simulator configuration window, click File > New Configuration.
4
Configure the simulator and LDD system for the test. Make sure you have discovered the simulator in the LDD
system and have deployed the solution to the simulator.
After the MFP simulator has been discovered, use the following settings in the MFP Simulator configuration window:
•
Configuration tab:
–
Number of MFPs to simulate—1
–
Repetitions—A number high enough to run at least an hour. The following typical throughputs on a server
with the recommended hardware may help determine a rough estimate:
Solution processing load
Typical
Heavy
Very heavy (OCR)
Note: Using less than the recommended RAM significantly reduces throughput. For example, a
dual‑processor server with only 2GB of RAM can process only 600–800 jobs per hour when using a
"heavy" solution.
