While this presentation is not a "tuning how-to", the concepts of Memory
Management cut across all operating systems.
The next meeting of the Delaware Valley Compaq User Group will be

Speaker: Our speaker has selected memory as a topic and will be covering
information applicable to OpenVMS, UNIX and Windows NT environments.
Richard Hawkes is a Principal Consultant with Geodesic Systems. He has a
bachelor of science degree with honors from Brown University in Computer
Science, and 16 years of industry experience with UNIX, Windows, and VMS.
Topic:
"Effective Memory Management: Improving Performance and Reliability in
Business Critical Server Applications."
Outline:
* Overview of the problem: many companies are putting their legacy
servers online as part of "webifying" their businesses. Many of these
applications are not robust and/or fast enough to handle 24x7 stress. We
will discuss what aspects of the memory management subsystem have the
biggest impact on this.
* Improving performance (definition and discussion of the benefits of
the following techniques):
* Size specific allocation:
* Reduces fragmentation
* Faster free list scans
* Locality of reference
* Reduced paging
* Footprint reduction
* Reduces overall memory use
* Better locality of reference for future allocations
* Free list coalescence
* Reduces fragmentation
* Reduces free list scans
* Multiple heaps
* Improves performance of multi-threaded apps
* Benefits are very apparent on SMP systems
* Improving reliability (definition and discussion of the benefits of
the following techniques):
* Dynamic memory leak correction (garbage collection)
* Premature free remediation
* Improving maintainability
* Importance of allocator configurability
* At application design time
* At run time
* Custom configurability
* Field replaceable allocator modules and their benefits
* "Open malloc" benefits
* Ease of integration: What an efficient allocator needs to do to
integrate seamlessly with an application
* Conclusion
