4.2 Load and processing
The following graphic compares the number of jobs being created in the print spooler (actual print jobs, blue
line) per minute, and how that relates to the number of messages being queued (beige line) during a 1 hour
period. For high-capacity analysis, refer to the Peak analysis section of this guide.
The number of queued messages indicates HP ePrint Enterprise capacity to process APJ’s when they arrive
for rendering. If this line indicated a growing trend (and not a stable range as in the graphic below), this
would mean a progressive increase of response time (i.e. there would be more queued messages per time).
This graphic indicates a stable ratio of submission and consumption during one hour, if 4 APJ’s are submitted
per minute.
HP ePrint Enterprise prints 4 APJ’s per minute without increase in waiting time per job. More APJ’s may be
submitted, but may present a different performance behavior.
4.3 Resource usage
The following graphic shows resource usage, submitting a base load of 4 APJ’s per minute to a single printer,
during 6 hours. As shown here, HP ePrint Enterprise resource usage fluctuates, but is capable of recovering
the same levels of memory consumption - even during a 6 hour period.
It was therefore observed that HP ePrint Enterprise does show any observable memory leak over the period
of 6 hours under a constant base load.
