Projects

APC

APC is a free, open, and robust framework for caching and optimizing PHP intermediate code.

The LLVM Compiler Infrastructure

LLVM is a robust system, particularly well suited for developing new mid-level language-independent analyses and optimizations of all sorts, including those that require extensive interprocedural analysis. LLVM is also a great target for front-end development for conventional or research programming ... [More] languages, including those which require compile-time, link-time, or run-time optimization for effective implementation, proper tail calls or garbage collection. We have an incomplete list of projects which have used LLVM for various purposes, showing that you can get up-and-running quickly with LLVM, giving time to do interesting things, even if you only have a semester in a University course. We also have a list of ideas for projects in LLVM. [Less]

XCache

XCache is a open-source opcode cacher, which means that it accelerates the performance of PHP on servers. It optimizes performance by removing the compilation time of PHP scripts by caching the compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This ... [More] will increase the rate of page generation time by up to 5 times as it also optimizes many other aspects of php scripts and reduce serverload. [Less]

eAccelerator

eAccelerator is a further development of the mmcache PHP accelerator and encoder. It increases the performance of PHP scripts by caching them in a compiled state, so that the overhead of compiling is almost completely eliminated.

JBoss Cache

JBoss Cache is a product designed to cache frequently accessed Java objects in order to dramatically improve the performance of applications. By eliminating unnecessary database access, JBoss Cache decreases network traffic and increases the scalability of applications. In addition, JBoss Cache ... [More] is a clustering library allowing you to transparently share objects across JVMs across a cluster. JBoss Cache provides three APIs to suit your needs. The Core API offers a tree-structured node-based cache. A POJO API provides the ability to perform fine-grained replication of Java objects, resulting in maximum performance benefits. Finally, a new Searchable API allows you to run object-based queries on the cache to search for cached objects. [Less]

pahole

Analyzes your code and identifies unused memory "holes" in data structures, and suggests re-ordering to improve memory usage and speed.

MySQLTuner

MySQLTuner is a high-performance MySQL tuning script written in perl that will provide you with a snapshot of a MySQL server’s health. Based on the statistics gathered, specific recommendations will be provided that will increase a MySQL server’s efficiency and performance. The script ... [More] gives you automated MySQL tuning that is on the level of what you would receive from a MySQL DBA. [Less]

HipHop for PHP

HipHop is a source code transformer which transforms PHP source code into highly optimized C++ and then compiles it using g++.

Combres

.NET library which enables minification, compression, combination, and caching of JavaScript and CSS resources for ASP.NET and ASP.NET MVC web applications. Simply put, it helps your applications rank better with YSlow and PageSpeed.

AutoXS

The purpose of this Perl module and its plugin modules is to speed up the execution of a program at the expense of a longer startup time. AutoXS::Accessor comes with this same distribution as an example plugin. AutoXS plugins use the B and B::Utils modules to scan all subroutines (or methods) in ... [More] the calling package for certain patterns. If a subroutine complies with such a pattern, it is replaced with an XS subroutine that has the same function. AutoXS::Accessor uses Class::XSAccessor to generate the fast replacement accessors. [Less]
