http_rrd_profiler is an HTTP testing/monitoring tool written in Python. It uses Python's httplib to send a GET request to a web resource and adds performance timing instrumentation between each step of the request/response. RRDTool is used for data storage and graph generation. RRDtool is an open source, high performance logging and graphing system for time-series data.
Local Code : Real Estates uses geospatial analysis to identify thousands of publicly owned abandoned sites in major US cities, imagining this distributed, vacant landscape as a new urban system. Using parametric design, a landscape proposal for each site is tailored to local conditions, optimizing thermal and hydrological performance to enhance the whole city’s ecology—and relieving burdens on existing infrastructure. Local Code’s quantifiable effects on energy usage and stormwater remediation eradicate the need for more expensive, yet invisible, sewer and electrical upgrades. In addition, the project uses citizen participation to conceive a new, more public infrastructure as well —a robust network of urban greenways with tangible benefits to the health and safety of every citizen.

Monarch is a set of libraries and tools for creating high-performance REST-based, native JSON Web Services. Monarch is best suited for sites that rely on thousands of AJAX calls per minute to provide their core functionality. For more information on Monarch performance, check out the blog posts at Digital Bazaar.

VertexDB is a high performance graph database server that supports automatic garbage collection. It uses the HTTP protocol for requests and JSON for it's response data format and the API is inspired by the FUSE filesystem API plus a few extra methods for queries and queues. It's implementation is currently built on top of TokyoCabinet and libevent.

This is a parser for HTTP messages written in C. It parses both requests and responses. The parser is designed to be used in performance HTTP applications. It does not make any allocations, it does not buffer data, and it can be interrupted at anytime. It only requires about 128 bytes of data per message stream (in a web server that is per connection).

BTW, Just a small rant... The Notes back end is way better than exchange. We were running 2000 users on One domino server with no issues. We have invested in 10 servers for outlook and over a mil in emc consulting. Personally I’m dumfounded at the decision to switch.
Oui mais Exchange c'est top : en plus des problèmes de performance côté serveur, on a les mêmes côté client avec cette bouse d'Outlook !
Here at Google, we believe programming should be fast, productive, and most importantly, fun. That's why we're excited to open source an experimental new language called Go. Go combines the development speed of working in a dynamic language like Python with the performance and safety of a compiled language like C or C++.
ealing with browser caching is a balancing act. On one hand, you aim to minimize load times and bandwidth use by ensuring that images, scripts, and style sheets are cached by your visitors; however, you still want to ensure that they’re accessing the most recent versions of all your files. In this article, I’ll show you a few methods for controlling how your site’s files are cached by browsers so you can achieve the best of both worlds: maintaining optimal performance while ensuring that any updates are seen immediately, without a hitch by all of your users.
Innovation in artistic process and expression is at the heart of the many initiatives being explored in the art, design and performance laboratories in the Faculty of Fine Arts.

Although we are not comparing apples to apples, Gentoo did out-perform Ubuntu in almost every test, and sometimes by a fair margin. It does appear that optimizing for a specific CPU can yield a decent performance increase.
Of course, Gentoo offers benefits in other areas with their USE flags and being able to build a highly customized system. The question is whether the amount of time it takes is worth the benefit, and that’s a personal choice.

The Wolfram|Alpha API gives you access to the Wolfram|Alpha platform at all levels—from individual results to complete Wolfram|Alpha output pages. The API operates as a high-performance REST-style webservice, with convenient bindings for all popular languages and platforms.
Developing Flowdock, a real-time environment allowing teams to work together seamlessly, we needed a database able to scale horizontally for huge amount of write operations. Cassandra’s data model and performance characteristics made it a perfect fit for our needs.
A couple of good things to remember here: #1 resolving 1 bottleneck can open another bottleneck that is much worse. #2 is to understand that not all API’s are created equal. Additionally the configuration and setup that works well on one system may not work well on another. Because of this people often leave lots of performance on the table. Don’t just trust that your current API or config is optimal, test and make sure it fits your application.
pour que memcached fonctionne vraiment, il faut que les données soient toutes dans le memcached.What, a performance regression? But we threw more memory at it!! How can that be!
Memcached is not a cure all.
A quick survey shows that seven of the Alexa U.S. top ten web sites have a SCRIPT tag above their stylesheets or STYLE blocks: AOL, Facebook, Google, Bing, MSN, MySpace, and Yahoo!. These web sites don’t currently use @font-face, but if they did, they would experience the IE blocked rendering problem. This raises the concern that other web sites that are early adopters of @font-face have a SCRIPT tag above @font-face and their IE users run the risk of experiencing blocked rendering.
