The Role and Benefits of HP WebQoS
HP WebQoS is an enhancement to the HP-UX operating environment
that stabilizes, optimizes, and prioritizes Internet-related applications
and transactions that run on HP 9000 Enterprise servers. HP WebQoS
works with web-enabled applications built on top of the iPlanet Web
Server

promotional, seasonal, or current events may instigate sudden and
immediate interest in your services. Although the additional interest
and business may be welcome, your server may not be able to handle
the load if significant numbers of clients come all at one time. Or if
you are a service provider hosting multiple sites on one server, you
should make sure that the demands of one site do not restrict use by
other sites on the same server.
• Heavier than expected system processing per user request.
The actual workloads exhibited by each visitor to your site may not
align with the workload models you generated during the capacity
planning stage. Perhaps users are performing far more searches than
you anticipated or are spending a lot more time performing compute
intensive operations while at your site.
• All requests are treated the same.
During overload conditions, all user requests and all transactions are
impacted. Even your most important customers who are trying to
access their accounts to make purchases, or sales representatives who
