How can I improve overall HP-UX system performance?
From the comp.sys.hp.hpux FAQ
with updated links from Robelle
There are, of course, many answers to this question. Many people have
noticed that HP's conservative choices in some configuration areas affect
performance, especially as compared to Solaris. A couple examples:
o 'fs_async' kernel parameter
HP-UX by default makes all file systems I/O synchronous. Sun[R],
by contrast, defaults to asynchronous I/O and depends on the
Changing this parameter's value from 0 to 1 can significantly
increase write speeds, BUT at the risk of losing data in a system
crash. You can change this parameter using SAM.
o 'async' NFS option
Similar to local writes, NFS writes to a filesystem exported from
HP-UX system are synchronous by default. Add the async option to
your /etc/exports if you want to change that, but be sure to
carefully read the exports(4) manpage first.
An abundance of performance tuning tips are provided by HP in the
o JFS Tuning and Performance (Journalized File System) August 2004.

Cupertino Acknowledges HP 3000
Glenn Cole writes:
Two years ago, a hotel and condos were built in front of the Cupertino
City Center at the busy Stevens Creek and De Anza Blvd intersection.
Earlier this year, a plaza was constructed with sculpture, benches
(with free wireless Internet access), fountains, and a few historical
markers. One of the markers is labelled Technology. It reads:
Since the 1960s, Cupertino has been at the leading edge of
technology. In the same pioneering spirit of the founders
of Cupertino, the companies and people of Cupertino have been
responsible for many of the advances in computers. Pictured
below is Hewlett-Packard's first general-purpose computer,
the HP3000, created in 1972; Apple Headquarters at One Infinite
Loop; and the first Apple computer created in 1976.

Firefox: Fight Worms and Spyware
The easiest way to eliminate spyware, adware and worms on your PC is to switch from the
Internet Explorer browser to the new Firefox browser from Mozilla (the open-source descendant of Netscape). Firefox Version 1 Preview Edition is reliable, does not have security holes like IE, and has almost zero learning curve; it imports your IE favorites, history, cookies, and plug-ins, including my Google toolbar. Even supports themes and skins. I have not run into any web pages that it cannot handle,
except for our Windows Terminal Services (perhaps we just need to install the plug-in).
Here is a typical
review and here is a
web site for Firefox help.
