HP Web Jetadmin - Performance and Threadpools in HP Web Jetadmin
OVERVIEW
HP Web Jetadmin is a powerful printer management software solution designed to install, configure,
troubleshoot, and manage a printer fleet. Sizing an HP Web Jetadmin installation and optimizing it
for performance can be challenging. There are many variables involved to provide an accurate
recommendation for number of devices. The hardware where HP Web Jetadmin is installed, enabled
features, and number of devices directly influence the performance of an HP Web Jetadmin
installation. This document discusses sizing an HP Web Jetadmin installation, features that affect
performance, troubleshooting performance issues, and how to potentially improve the performance of
many tasks in HP Web Jetadmin by manipulating the number of threads used for each task.
SIZING
A very common question when initially implementing HP Web Jetadmin is “How many devices can I
include in my installation?” The question seems simple, but the answer is complex. HP Web Jetadmin
contains a great deal of functionality and feature sets that vary in both resource requirements and
performance expectations. HP Web Jetadmin is not a one-size-fits-all type of solution. The hardware
where HP Web Jetadmin is installed directly influences the answer. The number of devices and types
of features certainly influence the answer. This paper does not provide an exact answer to this
question. However, it does examine features that affect sizing and performance and provides
examples of number of devices tested in various scenarios by the HP Web Jetadmin test lab for
comparison purposes. The true number of supported devices on any given HP Web Jetadmin
installation depends on many factors, beginning with hardware.
HARDWARE REQUIREMENTS
Performance in HP Web Jetadmin is only as powerful as the hardware where HP Web Jetadmin is
installed. Commercial implementations of HP Web Jetadmin function much better on server class
hosts. Disk system performance is also critical to the operation of HP Web Jetadmin. Much of the disk
activity is tied to HP Web Jetadmin interacting with a Microsoft
®
SQL Server database instance. High
performance storage speeds up these operations and helps the application run much better.
Server hardware
HP recommends the following server hardware configuration:
4 or more processor cores
2.8 GHz or higher processor speed
4 GB or more of RAM
4 GB of available storage
HP highly recommends a 64-bit system.
Virtual machines
For VMware environments, appropriate processors and RAM must be dedicated for each virtual
machine. For a VMware server, the virtual machine network must be set to bridged to facilitate
HP Web Jetadmin communications. It is very important to configure VMware so that its guest or virtual
systems have enough resources to support HP Web Jetadmin and Microsoft SQL Server. To ensure
that the appropriate resources are provisioned, see the support documentation for the VMware
version you are using.
