Performance tuning - Wikipedia, the free encyclopedia Performance tuning is the improvement of system performance. Caching is an effective manner of improving performance in situations where the principle of locality of reference applies. High performance cluster computing is a well known use of distributed systems for performance improvements. en.wikipedia.org /wiki/Performance_tuning   (665 words)

Performance Tuning Without effective performance management and tuning, the efforts of IT to wring costs out of the data warehousing infrastructure are essentially wasted. In many environments, the simple and often only answer to performance challenges is to "add a server to the cluster", or "buy another node", or "add memory to the machine". Executed correctly, performance management is the ongoing process of actively monitoring key system functions and metrics and using the information to adjust your business intelligence system for optimal performance. www.claraview.com /?p=performance_tuning_extending_bi   (211 words)

Introduction to Domino performance tuning Performance tuning options on Domino servers with more than one CPU and multiple hard drives is obviously more involved. Performance tuning of these systems involves setting up the disk drive partitions, and arranging the system, program, and data directories to distribute the workload across the system as evenly as possible. Performance testing clogs the weak points in your system by creating an e-mail "rush hour." Then the operating system performance statistics are used like traffic webcams to spy on the data flowing through the system. www-128.ibm.com /developerworks/lotus/library/ls-perf_intro   (2400 words)

Graphics Performance Tuning/Web Developer® Vol. 1 No. 1 -- October 1995   (Site not responding. Last check: 2007-10-13) Never lose sight of the fact that performance is very much a matter of perception. Conversely, one of the most abused "performance" tricks used on the Web is the use of interlaced graphics. I know I will get a lot of mail on this, but in real-world performance, the amount of time taken by many browsers when displaying multiple images of non-uniform size can take significantly longer when interlacing is used. www.webdeveloper.com /design/design_performance_tuning_rww.html   (1072 words)

Tuning your server for optimal Drupal performance | drupal.org   (Site not responding. Last check: 2007-10-13) The performance of your Drupal site is dependent on three main factors: the goals of your site, the resource demands of your site traffic, and the system performance and configuration of underlying technologies. This LAMP performance study revealed that Apache is bandwidth limited, PHP is CPU limited, and MySQL is memory limited and disk I/O bound. There are several known performance issues in Drupal 4.6.5 including the URL alias table is loaded into memory frequently and the use of Path and PathAuto modules will lead to an increase in the number of aliases in the table(patch available for URL alias table). drupal.org /node/2601   (1116 words)

Computer Performance Tuning Mercury's Performance Tuning Network at tuning.merc-int.com is not operational. Java 2 Performance and Idiom Guide (Prentice Hall, September, 1999) by Craig Larman and Rhett Guthrie is an almanac for the advanced programmer based on Java 1.1, but still mostly relevant. Profiling is the cental task to performance tuning because it identifies the frequency of class and method invocations, which provides a way to prioritize code optimization efforts that can be very time-consuming. www.wilsonmar.com /perftune.htm   (4067 words)

Sun Java System Message Queue Software Performance Tuning: An Overview Performance tuning is an iterative process of both developing an application that uses Sun ONE Message Queue software and configuring the software system to meet performance goals. Benchmarking and tuning allow developers to determine if the application meets their original requirements and if not, make changes in the configuration of the system to try to reach the performance goals. Tuning is a process of altering configurable parameters in the broker. developers.sun.com /sw/docs/articles/integration/tuning_overview.html   (965 words)

oreilly.com -- Online Catalog: Java Performance Tuning, Second Edition Java Performance Tuning teaches you to work efficiently and effectively, resulting in code that is robust, maintainable, and fast. Java Performance Tuning would be a good book to have if you have a seriously performance intensive application or for someone who just really dug performance issues. Eight years is a long time in our industry--long enough for two generations of undergraduates to have it as a first language, and long enough for books about it to go into their second edition, which is a welcome thing, because by and large, only good books are updated and reprinted. www.oreilly.com /catalog/javapt2   (712 words)

Postfix Performance Tuning Optimize the mail submission rate by tuning the number of parallel submissions and/or by tuning the Postfix in_flow_delay parameter setting. The tuning of the inbound concurrency limits need not be trial and error. When a Postfix delivery agent (smtp(8), local(8), etc.) is unable to deliver a message it may blame the message itself, or it may blame the receiving party. www.postfix.org /TUNING_README.html   (2834 words)

Enabling High Performance Data Transfers [PSC]   (Site not responding. Last check: 2007-10-13) Applications sometimes perform poorly on long paths (even when the network is perfect) because they are not designed to fully overlap the speed of light delay to deliver the data with the processing at the end systems. Under High Performance Networking Options we describe each of the optional TCP features may have to configured without addressing the details of any specific operating system. But these high performance options are sometimes not enabled by default and will have to be explicitly turned on by the system administrators. www.psc.edu /networking/perf_tune.html   (4461 words)

Oracle FAQ: Oracle Monitoring and Performance Tuning One of the biggest responsibilities of a DBA is to ensure that the Oracle database is tuned properly. Statspack is a set of performance monitoring and reporting utilities provided by Oracle from Oracle8i and above. Generate a current explain plan of the offending query and compare it to a previous one that was taken when the query was performing well. www.orafaq.com /faqdbapf.htm   (2148 words)

Performance Tuning PostgreSQL There isn't much you can tune about this step, however if you have a very large queries that cannot be prepared in advance it may help to put them into the database as a stored procedure and cut the data transfer down to a minimum. While there aren't any real tuning options for this step, you should be aware that all of the data that you are returning is pulled from the disk and sent over the wire to your client. Depending on your application it may be better to deny the connection entirely rather than degrade the performance of all of the other children. revsys.com /writings/postgresql-performance.html   (3251 words)

Cisco - Performance Tuning Basics In tuning a router's performance, your objective is to minimize the time a packet remains in a router. The legacy method for forwarding packets (by looking for a longest match in the routing table) cannot be implemented at interrupt level and must be performed at process level. In order to perform an exact-match-lookup at interrupt level, the routing table has to be transformed to use a memory structure convenient for this kind of lookup. www.cisco.com /warp/public/63/tuning.html   (2787 words)

Database - Performance Tuning As most business applications are heavily dependent on the very human elements of creating, entering, maintaining and retrieving data as a central feature of their operation, the DBA often is the first suspected source of a database problem. IT managers and industry experts agree that poor performing SQL is responsible for approximately 80 percent of response-time SLA failures. BMC Software’s performance tuning solutions allow the DBA to closely examine system and application issues for the root cause of a performance problem. www.bmc.com /products/products_services_detail/0,,0_0_0_1501,00.html   (626 words)

performance: Tuning JVM switches for performance The documentation of Sun's JDK 5 and newer refers to Trouble-Shooting and Diagnostic Guide containing many tips how to find problems that are often related to performance. The measurements supporting the use of this algorithm can be found on the performance website. The reported result is snappier performance once the IDE is running, since more of the UI code will be compiled rather than interpreted. performance.netbeans.org /howto/jvmswitches/index.html   (1043 words)

- Performance Tuning - There is still hope for performance tuning these cars. Another performance option is a larger throttle body from RPW in Australia. One of the first upgrades that a 5-speed owner should perform is replacing the transmission gear oil. www.mirage-performance.com /old-site/tuning.html   (1102 words)

Tuning Mac OS X Performance If performance is critical, disable the automatic protection features of such utilities, usually via their Preferences. While Mac OS X is relatively maintenance-free, by regularly performing the tasks outline in our "Maintaining Mac OS X" FAQ, you will help assure the best performance from your system. If you are using a laptop on battery power, increasing the processor performance will shorten the amount of time you can use the computer at the battery's current state of charge. www.thexlab.com /faqs/performance.html   (1230 words)

Apache Performance Tuning - Apache HTTP Server Many OS suppliers have introduced significant performance improvements to their TCP stacks and thread libraries in recent years. But it has such a drastic effect on the perceived performance of Apache that it had to be replaced. Since memory usage is such an important consideration in performance, you should attempt to eliminate modules that youare not actually using. httpd.apache.org /docs/2.0/misc/perf-tuning.html   (4052 words)

mod_perl: Performance Tuning You might tune your scripts and webserver to process incoming requests ultra quickly, so you will need only a small number of working servers, but you might find that the server processes are all busy waiting for slow clients to accept their responses. Very important aspect of performance tuning is to make sure that your applications don't use much memory, since if they do you cannot run many servers and therefore in most cases under a heavy load the overall performance degrades. So imagine that you have this 10Mb in-memory database that resides in a single variable, you perform various operations on it and want to make sure that the variable is still shared. perl.apache.org /docs/1.0/guide/performance.html   (9746 words)

Performance Tuning This approach is not enough for solving the performance problems of complex architectures. Commons Pool, from the Apache Software Foundation, may not be the first when it comes to implementation, but it deserves its own place for defining a framework that allows any arbitrary object to be pooled. This operation's performance often proves suboptimal, because of object churning: complex objects are created, used, and garbage-collected by the JVM with every user request. www.javaworld.com /channel_content/jw-performance-index.html   (941 words)
