We'll present the architecture and implementation of a Node.js/DTrace-based distributed platform for analyzing the performance of cloud applications in real-time. We'll do a live demo on a real, internet-facing cloud and discuss some of the interesting performance pathologies we've found and explained using this tool.
With most modern web applications, there are requirements for both SQL access to complex data as well as simple Key-Value look-ups. This session will cover how to use the HandlerSocket Plug-In for MySQL to get exponentially faster look-ups for simple access patterns.
There are many exciting InnoDB performance and Scalability features in MySQL 5.5 and its upcoming release. But how to best use them? What are the caveats? At this session, we will describe those performance and Scalability features in depth. We will also present some benchmark results that explore the performance of those features.
JRuby is just a Ruby implementation for the JVM, right? Wrong! JRuby has gone well beyond other language implementations by supporting arbitrarily-encoded strings, native library calls, reloadable applications, and much more. This talk will explore how JRuby is pushing the JVM and Java platform in new directions, and how you can take advantage of this new power.
Discover a variety of creative techniques for dramatically improving page load speed which focus on low-hanging fruit rather than micro-optimization, and what impact they had when applied to the world's fifth largest website, Wikipedia. Trevor and Roan will explore optimization beyond server load, minification and gzip, and offer up new open source libraries to help others do the same.
With the prevalence of multi-core systems and virtualization, several assumptions made during the design & optimization of PHP & APC are no longer valid. This talk covers the basic under-the-hood changes that have gone into making PHP perform better on multiple cores & virtualized environments.
Identifying code bottlenecks is a relatively simple endeavor. However, in this presentation we will look at identifying and fixing performance issues that are related to infrastructure/operational issues as well as looking at code, along with providing some best practices that can help ensure that your PHP application is running along at an optimal speed.
Techniques and tools to used to profile software applications. Examples and usage of OProfile, Google Profiler, Valgrind's Callgrind, and strace, geared towards profiling C/C++ applications. People should come away with the knowledge of what tools are available and how to diagnose performance issues in software.
Writing SQL is has very little in common with writing application code. Refactoring SQL has nothing in common with writing application code. Good object-oriented refactoring techniques frequently cause problems with SQL. This talk covers tried and true methods for refactoring SQL.
Tornado is a scalable, non-blocking web server and web application framework written in Python. It is also light-weight to deploy, fun to write for, and incredibly powerful. So why aren't you using it?
This presentation will cover the basics of the framework, as well as some best practices and real-life use cases.
An application that works great in development and test can be crushed by real-life deployment. Don't let your project be one of them. In a hands-on workshop, fix a (realistically) broken Django example so that it can hold its head high under load.
