Projects tagged ‘optimization’

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

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 ... [More] analysis. LLVM is also a great target for front-end development for conventional or research programming 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 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 ... [More] compiled state of PHP scripts into the shm (RAM) and uses the compiled version straight from the RAM. This 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]

The YUI Compressor is JavaScript minifier designed to be 100% safe and yield a higher compression ratio than most other tools. Tests on the YUI Library have shown savings of over 20% compared to JSMin ... [More] (becoming 10% after HTTP compression). Starting with version 2.0, the YUI Compressor is also able to compress CSS files by using a port of Isaac Schlueter's regular-expression-based CSS minifier [Less]

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 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 ... [More] decreases network traffic and increases the scalability of applications. In addition, JBoss Cache 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]

Combines, minifies, and caches JavaScript and CSS files on demand to speed up page loads.

jhc is a haskell compiler which aims to produce the most efficient programs possible via whole program analysis and other optimizations.

pycallgraph is a Python library that creates call graphs for Python programs.

pack:tag is a JSP-Taglib that minifies, compresses and combines resources (like JavaScript and CSS) and caches them in memory or in a generated file. It works transparent to the user/developer and the compressing-algorithms are pluggable.
