General considerations
The current chapter contains the results of InfoPrint Manager performance testing. The tests meant to determine how the system reacts in terms of responsiveness and stability under a particular workload.
You must consider the requirements for an InfoPrint Manager system as a total entity. Remember that the product is dependent on the hardware configuration to process the workload accordingly.
Consider these areas:
-
Processor capacity
-
Application requirements
-
Anticipated growth requirements
-
I/O slot requirements (HDD, network, bus, etc.)
-
System memory
The application related factors that affect performance are:
- Number of jobs
- Average job size
- Number of pdservers
- Number of queues
- Number of actual destinations that are printing jobs at any given moment
- Actual destinations types (PSF, AIX, CUPS)
The following graphic is valid for any InfoPrint Manager usage type:
The memory usage related to the number of jobs on AIX
The memory usage related to the number of jobs on Linux
- Important:
-
For best results on AIX, the maximum recommended memory size for the InfoPrint Manager server must not be higher than 1400 MB. For more then 1400 MB, a new pdserver is needed.
-
For best results on Linux, the maximum recommended virtual memory size for the InfoPrint Manager server must not be higher than 3200 MB. For more then 3200 MB, a new pdserver is needed.
-
Consider adding a new pdserver on the same system to balance the workload only if the hardware configuration allows. For more informations about the hardware configuration, see AIX operating system and hardware tuning or Linux operating system and hardware tuning, depending on the operating system.
-
The memory used by the pdserver directly depends to the number of jobs, actual destinations, and queues. For informations about the virtual memory, see InfoPrint Manager server memory
