HP Web Jetadmin - Performance and Threadpools in HP Web Jetadmin

64-bit vs. 32-bit
Recent software improvements in HP Web Jetadmin have increased resource capacity requirements.
HP strongly recommends the 64-bit editions of Windows for production HP Web Jetadmin
installations:
 Microsoft Windows Server 2008 (R2 or 64-bit edition)
 Microsoft Windows Server 2003 SP2 or later (64-bit edition)
 Microsoft Windows 7 (64-bit edition)
32-bit systems cannot manage memory effectively enough to handle the memory usage that HP Web
Jetadmin requires.
Memory
RAM paging is a process that Windows uses when it runs out of RAM (memory). If HP Web Jetadmin
runs on a host that runs out of RAM and begins RAM paging, the application responds very slowly.
The UI is very sluggish. Most of the applications on the host are also sluggish. Steps can be taken to
troubleshoot this problem. Free memory can be observed through Windows Task Manager,
Performance tab, Physical Memory, Available. More memory might need to be added if available
memory is low. Performance counters can be used to see if HP Web Jetadmin or the database needs
additional memory. See Appendix B for more information. Running the client on a separate machine
than the HP Web Jetadmin server can also help.
The Windows default maximum paging file size might be inadequate, even on 64-bit systems, for
large HP Web Jetadmin installations that support thousands of devices. When this happens, Windows
might be unable to fulfill requests for additional memory, causing the HPWJA Service to fail. The
Windows 7 paging file size is configured in the Virtual Memory dialog of the Advanced Performance
Options tab of the Advanced System Properties settings.
